Answer: the minimum number of males over age 25 they must include in their sample n = 306
Step-by-step explanation:
Given;
Mean of milk consumption = 2.5litres
Maximum error E = 0.07
Variance S = 1.21 litres
Confidence interval of 85%
Z' = t(0.075)= 1.44
the minimum number of males over age 25 they must include in their sample = n
n = (Z'×S/E)^2
n = ( 1.44 × 0.85/0.07)^2
n = (17.4857)^2
n = 305.75
n = 306
