d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. O We reject the null hypothesis, since the p-value is not less than the significance level. O we fail to reject the null hypothesis, since the p-value is less than the significance level. Owe fail to reject the null hypothesis, since the p-value is not less than the significance level.

Question
The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record
stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia.
According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that
the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the
fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for
54 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of
the fish in the John H. Kerr Reservoir is greater than 40 pounds.
n = 54; x = 40.66 pounds; s = 3.97 pounds

f) Do you reject the null hypothesis?
O We reject the null hypothesis, since the p-value is less than the significance level.
We reject the null hypothesis, since the p-value is not less than the significance level.
We fail to reject the null hypothesis, since the p-value is less than the significance level.
We fail to reject the null hypothesis, since the p-value is not less than the significance level.
g) Select the statement below that best represents the conclusion that can be made.
There is sufficient evidence to warrant rejection of the claim that the mean weight of the fish in the John
H. Kerr Reservoir is greater than 40 pounds.
There is not sufficient evidence to warrant rejection of the claim that the mean weight of the fish in the
John H. Kerr Reservoir is greater than 40 pounds.
The sample data support the claim that the mean weight of the fish in the John H. Kerr Reservoir is
greater than 40 pounds.
There is not sufficient sample evidence to support the claim that the mean weight of the fish in the John
H. Kerr Reservoir is greater than 40 pounds.
