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
43 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 = 43; x =
40.49 pounds; s = 2.89 pounds
a) Identify the null and alternative hypotheses?
Ho: ?
H₁: ?
b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)?
O left-tailed
right-tailed
two-tailed
c) Identify the appropriate significance level.
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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F509e5958-8244-4a2f-8465-f7fef11461d8%2F34758629-87d5-48e2-aec6-722f171078ab%2F2huf6w8_processed.png&w=3840&q=75)
