Question

A consumer's group randomly samples 10 " fifteen-ounce" packages of ground beef sold by a supermarket. The weights, in ounces, are 14, 14, 13, 15, 14, 14, 13, 15, 13, and 15. Assuming normality, test at the 0.05 significance level the claim that the packages actually weigh less than 15 ounces. x: Use 3 decimal places Ho: P-value Do not answer until you choose an Do not answer until you choose an You cannot answer this until you choose an -You cannot answer this until you choose an O You cannot answer this until you choose an You cannot answer this until you choose an

Explanation / Answer

x bar = 14

s = 0.816

H0: Mu = 15

Ha: Mu < 15

Alpha = 0.05

Test statistic t = (14 - 15)/[0.816/Sqrt(15)] = -4.746 (it is -4.75 rounded to 2 decimal places)

p value(1 tail) at t = -4.75 for df = n - 1 = 14 is 0.0002
