Here the question is to solve this anova problem by technology tool so you can use minitab software also. Here the steps for solving one way anova problem by minitab:-
1) enter the given observation corresponding to 4 variable of GPAs in 4 different column.
2) click on stat-anova-one way
3) select the 4 variable in responses "in sample column"
4) click on ok.
After running the above steps in minitab you get the anova table.
And this is the link for a youtube video for solving this problem ti 84

10. A science teacher claims that the mean scores on a science assessment test for fourth grade boys and girls are equal. The mean score for 13 randomly selected boys is 151 with a standard deviation of 36, and the mean score for 15 randomly selected girls is 149 with a standard deviation of 34. At a 0.01, can you reject the teacher's claim? Assume the populations are normally distributed and the population variances are not equal. Но Type of...

Use the magnitudes (Richter scale) of the 120 earthquakes listed in the accompanying data table. Use technology to find the range, variance, and standard deviation. If another value, 7.00 , is added to those listed in the data set, do the measures of variation change much? .

In determining the total variation, there are: determining the among-group variation, there are 4 degrees freedom. In determining the within-group variation, there are 20 degrees of degrees of freedom. Also, note that SSA 96, SsW 120, SST = 216, MSA 24. MSW 6, and FSTAT 4. Complete parts (a) through (d).
