Can you include degree of freedom in part B and not part D please

V Espanol It seems these days that college graduates who are employed full-time work more than 40-hour weeks. Data are available that can help us dedde If this Is true. A survey was recently sent to a group of adults selected at random. There were 12 respondents who were college graduates employed full-time. The mean number of hours worked per week by these 12 respondents was 42 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 J. Can we conclude that JI Is greater than 40 hours? Use the 0:10 level of significance. Perform a one-talled test. Then complete the parts below. Carry your Intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) M (3) State the null hypothesis Ho and the alternative hypothesis H- H H :0 S (b) Determine the type of test statistic to use. Degrees of freedom: D=0 OSO 020 (c) Find the value of the test statistic. (Round to three or more decimal places.) 0=0 00 X (d) Find the p-value. (Round to three or more decimal places.) ? (e) Can we conclude, at the 0.10 level of significance, that the mean number of hours worked per week by college graduates is greater than 40 hours? Yes ONO
