Answer: D. The total sample size is too large to apply the chi-square test for homogeneity.
Step-by-step explanation: When sampling without replacement, the sample size should not exceed 10 percent of the population size. Here, the sample size of 85 is just over 24 percent of the population of 350 company employees.
The total sample size is too large to apply the chi-square test for homogeneity.
We have given that,
A manufacturing company with 350 employees is changing the employee health insurance plan to either plan A or plan B.
Plan A Plan B Total
yes(group 1) 40(32.5) 20(27.5) 60
No (group 2) 6 (13.5) (11.5) 25 25
Total 46 39 85
We have to find which statement is true,
What is sampling without replacement?Each sample unit of the population has only one chance to be selected in the sample. we can select one sample only way and after selection we cannot pot this sample in the sample space again.
The sample size should not exceed 10 percent of the population size.when we use sampling without replacement,
Here, the sample size of 85 is just over 25 percent of the population of 350 company employees.
Therefore,the total sample size is too large to apply the chi-square test for homogeneity.

Use tangent:
tan = opposite / adjacent
tan x = 1/14x = arctan (1/14)x = 4°Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?
9514 1404 393
Answer:
20 minutes
Step-by-step explanation:
The trains are separating at the rate of 80 +70 = 150 km/hour. The time required to be 50 km apart is then ...
time = distance/speed = (50 km)/(150 km/h) = 1/3 h = 20 minutes

n =
9514 1404 393
Answer:
n = 4
Step-by-step explanation:
Of the 40 people, half are women, so there are 20 women.
There are 5 times as many women as men, so 20/5 = 4 are men.
The remainder are children, so there are 20-4 = 16 children.
The ratio of children to men is ...
children : men = 16 : 4 = 4 : 1 = n : 1 . . . . . . . . remove a factor of 4 from 16:4
The value of n is 4.
Use the figure to find the measures of the numbered angles.

This question is asking us to find the sum of [tex]4(3)^{n-1}[/tex] from n = 1 to n = 6. We can find the sum like this:
[tex]4(3)^{1-1} +4(3)^{2-1} +4(3)^{3-1} +4(3)^{4-1} +4(3)^{5-1} +4(3)^{6-1}[/tex]
Which can be simplified to:
[tex]4(3)^{0} +4(3)^{1} +4(3)^{2} +4(3)^{3} +4(3)^{4} +4(3)^{5}[/tex]
[tex]4(1) +4(3) +4(9) +4(27)+4(81) +4(243)[/tex]
[tex]4 +12 +36 +108+324 +972 = 1456[/tex]

The formula used for moving average is
a1= 1/4 ( W1+W2+W3+W4)
a2= 1/4 ( W2+W3+W4+ W5)
a3= 1/4( W3+W4+ W5+W6)
and so on
Where W1= week 1, W2= week 2 ,W3= week3
a1= 1st average , a2= 2nd average
The similar process is used for five year moving average
a1= 1/5 ( W1+W2+W3+W4)
a2= 1/5 ( W2+W3+W4+ W5)
a3= 1/5( W3+W4+ W5+W6)
Only it is divided by 5 instead of 4
To calculate the four-week and five-week moving averages, we need to sum up the sales for the specified number of weeks and divide by the corresponding period.
Week | Sales | 4-Period Moving Average | 5-Period Moving Average
-----|-------|------------------------|------------------------
1 | 17 | |
2 | 21 | |
3 | 19 | |
4 | 23 | |
5 | 18 | 20.00 |
6 | 16 | 19.25 |
7 | 20 | 19.50 |
8 | 18 | 19.25 |
9 | 22 | 19.00 |
10 | 20 | 19.00 |
11 | 15 | 18.75 | 19.20
12 | 22 | 18.75 | 19.20
13 | 22 | 19.75 | 19.40
14 | | 19.75 | 19.40
15 | | 19.75 | 19.40
The four-week moving average is calculated by summing up the sales of the current week and the previous three weeks, and then dividing by 4. The five-week moving average is calculated similarly, but with a period of five weeks.

Well, let's break it down.
Since calculating a triangle is like calculating a rectangle, then sawing it in half, we can correctly decide that the top and bottom right sections are both equal to twelve, adding up to 24. Now for the other two, we can use another quick trick; by instead of adding the equal right triangles, you can skip the division and multiplication by two, leaving us with a square area of 16. 24 + 16 is 40, and since we are working with millimeters instead of meters, the answer must be D
