The mean number of hours worked per week by these 15 respondents was 41 hours, with a standard deviation of 10 hours. Assume that the population of hours worked per week by college graduates employed full-time is normally distributed with mean . Can we conclude that is greater than 40 hours? Use the 0.1 level of significance. Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas The null hypothesis: Ho 0 The alternative hypothesis: 8 720 The type of test statistic: The value of the test statistic: (Round to at least three decimal places.) The critical value at the 0.1 level of significance: (Round to at least three decimal places.) FACU! 10010 7 (Choose one) 0 0 2 DEO -- X 6 ?
