A company claims that the mean weight per apple they ship is 120 grams with a standard deviation of 12 grams. Data generated from a sample of 49 apples randomly selected from a shipment indicated a mean weight of 122.5 grams per apple. Is there sufficient evidence to reject the company’s claim? (useα = 0.05) 

A. Ho: µ = 120; Ha: µ < 120; Rejection Region: z < -1.64

B. Ho: µ = 120; Ha: µ < 120; Rejection Region: t < -1.80

C. Ho: µ = 120; Ha: µ > 120; Rejection Region: z > 1.64

D. Ho: µ = 120; Ha: µ ≠ 120; Rejection Region: z < -1.96 or z > 1.96

E. Ho: µ = 120; Ha: µ ≠ 120; Rejection Region: t < -2.20 or t > 2.20
