Help please! I don't know how to do this. Suppose 240 nursing students took a certification test that is worth 140 points. The five-number summary for the scores is shown here.

min. value = 68

Q1 = 110

median = 125

Q3 = 130

max. value = 138

About how many students had a score of 130 or less?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
