Is the mean weight of female college students still 59.4 kg? To test this, you take a random sample of 20 students, finding a mean of 61.65 kg with a standard deviation of 6.39 kg. Suppose the necessarily assumptions are satisfied, use a significance level of 0.10 to perform a significance test. A Fail to reject with 0.05 < P-value < 0.10. There is not sufficient evidence that the mean weight of female students has changed. B Fail to reject with 0.10 < P-value < 0.20. There is not sufficient evidence that the mean weight of female students has changed. C Reject with 0.05 < P-value < 0.10. There is sufficient evidence that the mean weight of female students has changed. D Reject with 0.10 < P-value < 0.20. There is sufficient evidence that the mean weight of female students has changed. E There is not enough information to perform the test.
