In order to conduct a hypothesis test for the population mean, a random sample of 9 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 5.3 and 1.4, respectively. Use the p-value approach to conduct the following tests at = 0.01.
A:
1. Calculate the value of the test statistic.
2. Approximate the p-value.
a. 0.020 < p-value < 0.050.
b. 0.010 < p-value < 0.020.
c. 0.050 < p-value < 0.100.
d. p-value < 0.01.
e. p-value Picture 0.1.
3. What is the conclusion?
A. Do not reject H0 since the p-value is greater than..
B. Do not reject H0 since the p-value is less than.
C. Reject H0 since the p-value is greater than.
D. Reject H0 since the p-value is less than.

c. 0.100 < p-value < 0.200.
d. p-value < 0.01.
e. p-value Picture 0.2.
