Hi I need help on what is the answers in my activity. Below is the question and a reference for activity B. I hope the you can help me and answers with explanation is highly recommended

Problem

A. Complete the table below and find the mean. (In order to complete the table just multiply X to P(X)). 1. X P(X) X *P(X) 1 3/8 3/8 = 0.375 2 2/8 1/2 = 0.5 3 1/8 3/8 = 0.375 4 3/8 3/2 = 1.5 5 1/8 5/8 = 0.625 Mean = H = 27/8 = 3.3752. X P(X) X *P(X) 10/33 10/33 = 0.3030 2 1/33 2/33 = 0.0606 3 12/33 12/11 = 1.0909 Mean = p = 16/11 = 1.45B. Complete the table below and find the variance and standard deviation of the following probability distributions. 2. X POO X-P(X) x .P(X) X P(X) X-P(X) X P(X) 1 2 3Direction: Read and analyze each problem. A. Find the z-score value that corresponds to each of the following given scores if u = 50 and g = 5 1. X - 75 6. X = 72.5 2. X - 45 7. X = 51 3. X -30 B. X - 62 4. X - 37.5 9. X -55 5. X - 80 10. X - 69
