Question

Construct a 99% confidence interval to estimate the population mean using the accompanying table. What assumptions need to be made to construct this interval? 

x(sample mean)= 82 

o(population standard deviation)= 20

n(sample size)= 16

What assumptions need to be made to construct this interval? 

a) the population is skewed to one side

b) the population mean will be in the confidence interval 

c) the sample size is less than 30 

d) the population must be normally distributed 

 

With 99% confidence, when n= 16, the population mean is between the lower limit of __ and the upper limit of __.
