need it fast!!!!!

solve e and f

the person who did before got wrong,

2. If an instructor accidentally makes an exam too difficult, one strategy is to
"mark on a curve". This is an application of the Z transformation.
Imagine an instructor teachirig a small class gives an exam to 20 students who
get the following marks (out of 100):
27 39 24 44 44 38 47 38 35 28
44 40 42 39 42 72 56 51
57 50
42.85 a. Compute the sample mean, M, for this sample
11.09 b. Compute the sample standard deviation, s, for this sample (round to 2
decimal places)
-1.70 c. Calculate the Z score for the lowest-scoring test (round to 2 decimal
places)
2.63 d. Calculate the Z score for the highest-scoring test (round to 2 decimal
places)
Suppose the instructor wished the class average to be 79 with a standard
deviation of 10, so they calculate the exam grades on the curve. After the
exam has been curved, it's possible for someone to get over 100.
e. Calculate the new exam score (out of 100) for the lowest-scoring test.
Round to the nearest integer
f. Calculate the new exam score (out of 100) for the highest-scoring
test.
Round to the nearest integer.
