c) Calculate the value of the test statistic.

d) Find the critical value for the appropriate test statistic.

e) Find the upper boundary of a 95% confidence interval of the mean chirp rate of male field crickets that was on a high protein diet for 8 days.

These are all under one question, please assist me as i am in need of great assistance and it will be appreciated. Thank you

Extracted text: The article "Well-Fed Crickets Bowl Maidens Over" (Nature Science Update, February 11, 1999) reported that female field crickets are attracted to males with high chirp rates and hypothesized that chirp rate is related to nutritional status. The usual chirp rate for male field crickets was reported to vary around a mean of 60 chirps per second. To investigate whether the chirp rate was related to nutritional status, investigators fed 25 male crickets a high protein diet for 8 days, after which chirp rate was measured. Let: The parameter u be the mean chirp rate of male crickets on a high protein diet for 8 days. Given: The mean chirp rate for the random sample of crickets on the high protein diet was reported to be 66.6 chirps per second with a standard deviation of 16. Research Question: Is there convincing evidence that the mean chirp rate for crickets on a high protein diet implies an advantage in attracting the ladies? It is known that the researchers did not want to risk a Type l error of more than 5%.
