The article "Well-Fed Crickets Bowl Maidens Over" (Nature Science Update, February 11, 1999) reported that female field crickets are attracted to m 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 h 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 deviat 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? • I t is known that the researchers did not want to risk a Type l error of more than 5%.

According to the critical value approach, it is evident that the null hypothesis is and there is that the mean chirp rate is higher for male field crickets that eat a high protein diet. f) Choose the correct interval for the p-value: O 0 < p-value < 0.005 O 0.005 < p-value < 0.01 O 0.01 < p-value < 0.025 O 0.025 < p-value < 0.05 O 0.05 < p-value < 0.1 O p-value > 0.1
