Course: Introduction to Statistics (Bus-172)Answer all the questions.Question: 1A company recently installed a new photocopy machine and evaluating how long it takes for newworkers to learn how to use the machine. Suppose it is known that the learning times for all newworkers have a skewed-to-the-right distribution with mean 90 minutes and standard deviationof 7 minutes. A sample of 36 workers are Selected.(a) What is the probability that the mean learning time of those sample of 36 workers is at least 98minutes?(b)What type of shape did you assume for the sampling distribution for sample mean and on whatground? Justify your answer.(c) If one worker starts to learn using the machine at 12 in the noon and the lunch time is 1:40pm,what is the probability that the worker will finish learning before lunch time.(d) Show both the population distribution and sampling distribution of sample mean in a single graph.Formulae:μπμ, στpqHô = p, Opx - µz =x – Hzz =p – Upz =Oß
