A test statistic for a two-sided significance test for a population mean is z=2.47. Sketch a standard Normal curve and mark this value of z on it. (Sketch does not need to be turned in.) Find the P-value and shade the appropriate areas under the curve to illustrate your calculations. (Sketch does not need to be turned in.) Report the P-value to 4 decimal places.

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
