2. The time (in number of days) until maturity of a certain variety of hot pepper is normally distributed, with mean m and standard deviation s = 2.4. This variety is advertised as taking 70 days to mature. I wish to test the hypotheses H0: m = 70, Ha: m > 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

79 76 72 73.

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 0.01.
c. I would reject H0 at level 0.01.
d. None of the above.
