5. A safety Engineer feels that 30% of all industrial accidents in her plant are caused by failure of employees to follow instructions. If this figure is correct, find, approximately, the probability that among 84 industrialized accidents in this plant ( a) anywhere from 20 to 30 (inclusive) will be due to failure of employees to follow instructions? (b) at most 25 failures will be due to failure of employees to follow instructions. (c) at least 16 failures will be due to failure of employees to follow instructions Use R to do this problem. Make sure to store each of the answer in a chosen variable, and display the results with proper title. (d) Now redo all three parts by using normal distribution approximation, after computing the mean and standard deviation, from the formulae given below. u= np and a = sqrt(np(1-p)) Repeat steps (a), (b) and (c) using normal distribution and verify the answers obtained above.
