    1. A multiple regression analysis includes 25 data points and 4 independent variables results in SST = 200 and SSR = 150. the multiple standard error of estimate will be?

    2. A professor claimed that the proportions of grades in his classes are the same. A sample of 100 students showed the following frequencies:

    grade A B C D F
    frequency 18 20 28 23 11

    Compute the chi-square test statistic for this problem.

    1. a multiple regression analysis includes 25 data points and 4 independent variables results in SST = 200 and SSR = 150. the multiple standard error of estimate will be?

    SSE = SST-SSR= 50 =200-150
    standard error of estimate= square root of (SSE/(n-k-1))= 1.5811 =square ...
