i need fixt it

For question 2a, check the “id” variable to be sure you have the correct cases numbers that need to be removed. There are three cases that should be removed that you did not list. Also, 18 and 1129 will automatically be removed since there is missing data for these cases (no MAH_1 value).

Some of your values are different than what I have. Be sure you run the multiple regression with the profile-b data set and only with cases that are MAH_1 ≤ 22.458.

For question 2h, you should not include the values for the variables that are not statistically significant. The regression equation should only include those variables that are statistically significant.

For 2i, also mention that these two variables are not statistically significant and provide the p (sig) value.
