The time (in days) until maturity of a certain variety of hot pepper is Normally distributed, with mean µ and standard
deviation o = 2.4. This variety is advertised as taking 70 days to mature. I wish to test the hypotheses Ho = 70,
H: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 76, 73, 69, and 70.
Based on these data:
None of the answer options are correct.
O I would reject Ho at level 0.01.
I would reject Ho at level 0.10 but not at level 0.05.
OI would reject Ho at level 0.05 but not at level 0.01.
