The average age of lifeguards in Ocean City is significantly greater than 24 years at a 5% level of significance.

What is Standard deviation?

Standard deviation is a measure of how spread out numbers are. It is the square root of the Variance, and the Variance is the average of the squared differences from the Mean.

To determine whether there is evidence to support the claim that the average age of lifeguards in Ocean City is greater than 24 years at a 5% level of significance, we need to perform a one-tailed t-test. A one-tailed t-test is used to test whether the mean of a sample is significantly greater than (or less than) a certain value.

To perform the t-test, we first need to calculate the t-statistic, which is defined as:

      [tex]t = (mean - null value) / (standard error / \sqrt{n} )[/tex]

where mean is the mean age of the sample of lifeguards, null value is the value that the null hypothesis is testing against (in this case, 24 years), standard error is the standard error of the mean age, and n is the number of lifeguards in the sample.

Plugging in the values from the problem, we get:

           [tex]t = (24.7 - 24) / (standard \ error / \sqrt{36} )\\\\= 0.7 / (standard\ error / 6)[/tex]

The standard error of the mean is a measure of the variability of the sample mean, and is calculated as:

   [tex]standard \ error = population \ standard\ deviation / \sqrt{(n)}[/tex]

Plugging in the values from the problem, we get:

standard error = / sqrt(36) = / 6 =

Substituting this value back into our expression for t, we get:

    t = 0.7 / ( 6)

      = 1.8

For a one-tailed t-test at a 5% level of significance, the critical value is 1.645. This means that if the t-statistic is greater than 1.645, we can reject the null hypothesis and conclude that there is evidence to support the claim.

So we can reject the null hypothesis and conclude that there is evidence to support the claim that the average age of lifeguards in Ocean City is significantly greater than 24 years at a 5% level of significance.

Santa's workshop staff traditionally consists of six elves with names. His elves construct the toys, wrap the presents, and craft the magic.

Manufacturing toys for Christmas presents, caring for the reindeer, baking cookies, making sweets, setting up Santa's sleigh, and helping Santa with other jobs are all responsibilities of a Christmas elf. Making toys all year long is one of the main responsibilities of Christmas elves.

They numbered 144 in total. Twelve became their base number and 144 their greatest number as all elves were discovered in groups of twelve (for a long time). There was no common name for a larger number in any of the later Elvish languages.

The area of the rectangle is 12 square units which vertices are P(2, 3), Q(4, -1), R(-8, -7), and S(-10, -3).

To find the area of the rectangle, we need to first find the side lengths of the rectangle. We can do this by using the coordinates of the points to find the distances between them.

The side length of the rectangle along the x-axis is the distance between points P and Q, which is 4 - 2 = 2 units.

The side length of the rectangle along the y-axis is the distance between points P and S, which is 3 - (-3) = 6 units.

Now that we know the side lengths of the rectangle, we can use the formula for the area of a rectangle, which is length x width, to find the area.

The area of the rectangle is 2 x 6 = 12 square units.

Therefore, the answer is 12 square units.

The equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

The equation y = 2x - 4 can be written in slope-intercept form as y = 2x + b, where b is the y-intercept. To find the slope and y-intercept of the equation, we need to solve for b.

The y-intercept is the point where the line crosses the y-axis. To find the y-intercept, we can set x equal to 0 in the equation to get y = 2(0) - 4. This simplifies to y = -4, so the y-intercept is -4.

The slope is the rate at which the line rises. To find the slope, we can take the coefficient of x, which is 2. So the slope of the equation y = 2x - 4 is 2.

In summary, the slope of the equation y = 2x - 4 is 2 and the y-intercept is -4. We can write the equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.

The level of a line's slope indicates its steepness.

The slope is computed mathematically as "rise over run" (change in y divided by change in x).

a) A procedure for identifying outliers is identifying if there are values that are more than 1.5 IQR from the quartiles. Thus, the value of 810 is an outlier in the given distribution.

b) As the distribution contains a high outlier, it means that the distribution is right skewed.

The first quartile of a data-set is the element that represents the 25th percentile of the distribution.

For a distribution of 34 students, the first half of the distribution has 16 values, hence the first quartile is the mean of the 8th and 9th values.

From the stemplot, these values are 170 and 180, hence:

Q1 = (170 + 180)/2 = 175.

The third quartile is the 75th percentile of the distribution, hence it is the mean of the 8th and 9th values of the second half of the distribution.

From the stemplot, these values are 39 and 41, hence:

Q3 = (390 + 410)/2 = 400.

The IQR is the difference between the quartiles, hence:

IQR = Q3 - Q1 = 400 - 175 = 225.

Values that are more than 1.5 IQR from the quartiles are considered outliers, hence the bounds are given as follows:

Hence the value of 810 is a high outlier. This high outlier will influence the mean, making it higher than the median, and thus the distribution is right skewed.

No, y = 4 is not a linear function.

A linear function is a function that has a constant rate of change, meaning for every input (x), the output (y) always increases or decreases by the same amount. This can be expressed algebraically as a linear equation in the form y = mx + b, where m is the rate of change (slope) and b is the y-intercept.

For example, y = 3x + 2 is a linear function because for every increase of 1 in the input (x), the output (y) increases by 3.

In contrast, y = 4 does not have a constant rate of change because the output (y) is always 4, no matter what the input (x) is. Therefore, y = 4 is not a linear function.

m=-2  ==> the slope is -2

y=mx+b  ==> slope-intercept equation

Discontinuous classes can be made continuous by using interpolation, which expression values between known points. For example, a discontinuous class of heights can be made continuous by using interpolation to estimate heights between known points.

Discontinuous classes can be made continuous by using interpolation. Interpolation is a mathematical process that estimates values between known points. This can be done in a variety of ways, such as linear interpolation which estimates values using the slope between two known points, or polynomial interpolation which uses a polynomial equation to estimate the values between known points. For example, if you have a discontinuous class of heights, you can use interpolation to estimate values between the known heights. This would result in a continuous class of heights, which may be more useful than the discontinuous class. Interpolation can also be used to estimate other types of values, such as temperature, pressure, or any other type of value that can be represented on a continuous scale.
