Grades	Female	Male
A	21.25%	29.51%
B	36.25%	31.15%

F	9.38%	11.48%

Do the letter grades from males differ from the letter grade of the females?

Solutions

Expert Solution

The two series are plotted and the differences are first observed in the line graph where Female vs Male is plotted.

Then the descriptive statistics are checked for their differences.

and finally a one tail T- test is used to compare both the series.

Since P(T<-t) is greater than 0.05, we conculde that the letter grades from males differ from the letter grade of the females.

Hope I clarified your query. Do let me know , your feedback on this.
