Find the minimum sample size n needed to estimate mu for the given values of c, sigma, and E. cequals0.90, sigmaequals7.5, and Eequals2 Assume that a preliminary sample has at least 30 members.
Solution :
Given that,
standard deviation = = 7.5
margin of error = E = 2
At 90% confidence level the z is ,
= 1 - 90% = 1 - 0.90 = 0.10
/ 2 = 0.10 / 2 = 0.05
Z/2 = Z0.05 = 1.645
Sample size = n = ((Z/2 * ) / E)2
= ((1.645 * 7.5 ) / 2)2
= 37.99
= 38
Sample size = 38
