The answer to the question is... 12
<span>a. verify that the conditions for computing a confidence interval are met in this case.
The formula for computing the CI interval is given by:
x_bar+/-z (s/</span>√n<span>)
since:
x_bar=6.67
s=1.88
n=15
The conditions are met because we have all the values necessary for computing CI.
b] </span><span> compute and interpret a 95% confidence interval for the mean number of hours the students at this school sleep each night.
The value of z corresponding to 95% CI is 1.96
thus the 95% CI will be:
6.67+/-1.96(1.88/</span>√15<span>)
=6.67+/-1.96(0.4854)
=6.67+/-0.9514</span>
