Responses should be a minimum of 100 words and may include direct questions. In peer responses, compare the probabilities that I found with those of my classmates. Were they higher/lower and why? In the responses, refer to the specific data from my classmates’ posts that I will include.PEER 1 (William): I thought the excel assignment for this weeks forum was easy to understand after completing last weeks assignment. The assignment asks us to find four different probabilities for the next 4 cars that are sampled. First, we must calculate a new standard deviation using the central limit theorem. In excel this looks like, =oldSD/SQRT(4) because the new sample size is 4. The new standard deviation is 13071.36, and I will use the same mean 36720.00.The first question asks us to find the probability that (x<36,220). In excel I enter =NORM.DIST(36220,36720,E18,TRUE) and get an answer of 48.47%. The second question asks us to find P(x>37,720). In excel this appears as =1-NORM.DIST(37720,E13,E18,TRUE) and receive an answer of 46.95%. The third question asks us to find P(x=36,720). In excel this appears as =NORM.DIST(E13,E13,E18,FALSE). The chances of this happening are very slim and we receive an answer of 0.00%. Finally, the assignment asks us to find P(35,220
