Question 10 Consider an operational process in a factory where widgets are produced. As the process is not perfect, errors sometimes happen, and the errors are either technical or human. Over the last 100 days, errors were observed and recorded. On any given day, there occurred zero to three (0 to 3) human errors and zero to three (0 to 3) technical errors. The frequency distribution of errors is given in the following contingency table. Number of human errors No. of Tech Errors 0 1 2 3 Total 0 8 6 4 4 22 1 5 8 9 10 32 2 4 5 10 8 27 3 0 3 4 12 19 Total 17 22 27 34 100 What is the probability of 0 technical errors given 3 human errors? State your answer as a decimal value rounded to two digits after the decimal point.

Hi, this problem is already reposted. However, not all items were answered before, so pls answer question 2 this time. PS. Since question 2 is related to question 1, I have also included the latter's answer below. Pls help me with this one. Thank you so much. *** A random sample was taken of the thickness of insulation in transformer windings, and the following thicknesses in millimeters were recorded: 1. a) Make a frequency table for these data starting at lowest lower class limit of 20 and with a class width/ class size of 7. b) Determine the class marks, class boundaries, relative frequency, <CF, and >CF.Note: You can use EXCEL. ✓✓ 2.From question 1, Draw the frequency histogram and ogives and make a short description about the shape of distribution.
