n = 380
mean = 1550
Sigma = 264
a.
90% CI is ? Z value for 99% CI is 1.645
Lower and Upper limit = Mean +/- Z*Sigma/sqrt(n)
= 1550 +/- 1.645*264/sqrt(380)
=1527.722 to 1572.278
b.
99% CI is ? Z value for 99% CI is 2.56
Lower and Upper limit = Mean +/- Z*Sigma/sqrt(n)
= 1550 +/- 2.56*264/sqrt(380)
=1515.33 to 1584.67
