Given: Sample size: n = 41
Sample mean
degrees
Population standard deviation
degrees
Confidence level (c) = 80% =0.80
Significance level (a) = 1- c = 1-0.80 = 0.20
z-score for 80% confidence level : z = 1.2816 [from z-table]
Confidence level for population mean :-







Hence, 80% confidence interval for the temperatures in the freezer 
This is a direct variation
C = pi*d
pi is a constant and it does thru (0,0)
