Construct a 95% confidence interval to estimate the population mean using the data below.

x=17

s=3.1

n=16

What assumptions need to be made about thispopulation?

The 95% confidence interval for the population mean is from a lower limit of

nothing

to an upper limit of

nothing

.

(Round to two decimal places asneeded.)

What assumptions need to be made to construct this interval?

a. the population is skewed to one side

b. the population must be normally distributed

c. the sample size is less than 30

d. the population mean will be in the confidence interval

With 95% confidence, when n=25 the population mean is between the lower limit of ___ and the upper limit of _____?
