The mean wait time for a sample of 145 male customers was 85.8 seconds. The mean wait time for a sample of 141 female customers was 113.4 seconds. The sample standard deviations (estimated from graphs that appeared in the paper) were 50 seconds for the sample of males and 75 seconds for the sample of females. For purposes of this exercise, suppose that these two samples are representative of the populations of wait times for female coffee shop customers and for male coffee shop customers. IL! SALT Is there convincing evidence that the mean wait time differs for males and females? Test the relevant hypotheses using a significance level of 0.05. (use males P-value to three decimal places.) df p_value = State pour conclusion. C) Fail to reject H . There is convincing evidence that the mean wait time differs for males and females. C) Fail to reject H . There is not convincing evidence that the mean wait time differs for males and females. C) Reject H . There is not convincing evidence that the mean wait time differs for males and females. C) Reject H . There is convincing evidence that the mean wait time differs for males and females. Round your test statistic to one decimal place, your df down to the nearest whole number, and your gfemales'
