Create one 90%, one 95%, and one 99.7% confidence interval for the question:

Last night did you get at least 8 hours of sleep?

Yes: 11

No: 48

Total: 59

Expert Solution

We have been provided with the following information about the number of favorable cases:

Favorable Cases X =	11
Sample Size N =	59

The sample proportion is computed as follows, based on the sample size N=59 and the number of favorable cases X=11:

a)

We need to construct the 90% confidence interval for the population proportion.

b)

We need to construct the 95% confidence interval for the population proportion.

c)

We need to construct the 99.7% confidence interval for the population proportion.

Problem: Construct and interpret a 90%, 95%, and 99% confidence interval for the mean heights of either adult females or the average height of adult males living in America. Do not mix genders in your sample as this will skew your results. Gather a random sample of size 30 of heights from your friends, family, church members, strangers, etc. by asking each individual in your sample his or her height. From your raw data convert individual heights to inches....
