Consider the following hypothesis from a sample of 22 observations that has the value ? = 2.24: ?0: ? = 8 ??: ? > 8

a. What are the degrees of freedom for this statistic?

b. Give the two critical values ? ∗ from t Distribution table that bracket t.

c. Between what two values does the P-value of the test fall?

d. Is the value ? = 2.24 statistically significant at the 5% level? Is it statistically significant at the 1% level?
