Question

The time (in number of days) until maturity of a certain variety of hot pepper is Normally distributed, with mean μ and standard deviation σ = 2.4. This variety is advertised as taking 70 days to mature. I wish to test the hypotheses H0: μ = 70, H1: μ ≠ 70, so I select a simple random sample of four plants of this variety and measure the time until maturity. The four times, in days, are 70 72 79 67

Based on these data

A) I would reject H0 at level 0.10 but not at level 0.05.

B) I would reject H0 at level 0.05 but not at level 0.025.

C) I would reject H0 at level 0.01.

D) None of the above
