Question

Quart cartons of milk should contain at least 32 ounces. A sample of 20 cartons contained the following amounts in ounces. Does sufficient evidence exist to conclude the mean amount of milk in cartons is less than 32 ounces at the 5% significance level?

The data is:   (32.5, 32.4, 31.8, 28.4, 27.3, 27.2, 28.3, 31.7, 32.8, 31.5, 27.5, 31.8, 28.6, 27.4, 31.7, 32.7, 28.7, 32.1, 32.3, 27.9)

Select the [p-value, Decision to Reject (RH₀) or Failure to Reject (FRH₀)].

a) [p-value = 0.001, FRH₀]

b) [p-value = 0.999, FRH₀]

c) [p-value = 0.999, RH₀]

d) [p-value = 0.001, RH₀]

e) [p-value = 0.000, RH₀]
