Assume that a sample is used to estimate a population proportion p. Find the margin of error M. E. that corresponds to a sample of size 329 with 49 successes at a confidence level of 99.5%.

The magin of error is 0.0552 = 5.52 percentage points.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

In which

z is the zscore that has a pvalue of .

The margin of error is:

For this problem, we have that:

99.5% confidence level

So , z is the value of Z that has a pvalue of , so .

M.E:

The magin of error is 0.0552 = 5.52 percentage points.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
