| Homework 13 | Due: Thurs. Oct 29th | A) Make 95% confidence intervals for
the mean and and for the variance for Table 4.5. B) Assume the standard deviations for the data from the two methods in table 5.14 are the same. Test the new mean = old mean and make a 99% CI for (new mean - old mean). C) Assume the data in Table 5.13 are paired. Test whether the value is greater with the device |
| Homework 14 | Due: Tues. Nov 17th | This homework assignment
uses the data in table 5.12 on page 210. Use SAS to answer the questions
and turn in copies of the program you ran and the output. A) For the new diet data, determine the 1st, 5th, 10th, 90th, 95th, and 99th percentile according to the method we used in class. B) Check that the new diet data is normal by using a histogram and normal curve, and by using a Q-Q plot. C) Test that the means and variances of the new and regular diet are equal, against the alternate hypothesis that they are not equal.
