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 whoget the following marks (out of 100):27 39 24 44 44 38 47 38 35 2844 40 42 39 42 72 56 5157 5042.85 a. Compute the sample mean, M, for this sample11.09 b. Compute the sample standard deviation, s, for this sample (round to 2decimal places)-1.70 c. Calculate the Z score for the lowest-scoring test (round to 2 decimalplaces)2.63 d. Calculate the Z score for the highest-scoring test (round to 2 decimalplaces)Suppose the instructor wished the class average to be 79 with a standarddeviation of 10, so they calculate the exam grades on the curve. After theexam 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 integerf. Calculate the new exam score (out of 100) for the highest-scoringtest.Round to the nearest integer.
