1) To obtain an estimate for the mean age of students enrolled in evening classes, a sample of 30 evening students was surveyed. The following is a list of the ages of the students in the sample. Type the data into a Minitab worksheet. 18 18 19 19 20 20 20 20 21 21 21 21 22 22 22 23 23 24 26 26 27 28 30 30 32 35 36 36 41 45 a) Give the point estimate for the mean age of students enrolled in evening classes. b) The age of students enrolled in evening classes is normally distributed. Give the 95% confidence interval for u. 2) The mean age of all evening students is reported by the local newspaper to be 24 years. Is there any evidence, at the 0.05 level of significance, to suggest that the mean age of students enrolled in evening classes is greater than that reported by the newspaper? Use the sample data above as evidence, and use Minitab to calculate the p-value. Make a decision about Ho and state the conclusion with regards to Hi. Null hypothesis: Alternative hypothesis: p-value from minitab: Compare p-value to alpha: State your conclusion
