The formula to calculate the confidence interval is given by :-
, where = sample mean.
z* = critical value.
= Population standard deviation.
n= Sample size.
As per given , we have
n= 217
By using z-table , the critical value for 95% confidence level : z* = 1.96
Now, the 95% confidence interval for the mean consumption of meat among males over age 50 will be :
Hence, the 95% confidence interval for the mean consumption of meat among males over age 50 =(3.3, 3.5)
