I need help solving some statistic problem. The problems are based on the Wilcoxon?signed-ranks test. You don't waste time explaining how to do the problem you just tell me the answer to the questions. Just do problems 5-7

A company's quality-control division is constantly monitoring various parameters related to its products. One investigation addressed the life of incandescent life bulbs (in hours). Initially, the division was satisfied with examining the average length of life. However, a recent sample taken from the production floor gave them pause for thought. Their initial efforts indicated that the average length of life of the light bulbs was 1,430 hours. Complete parts a and b below. Click the icon to view the data on the length of life of incandescent life bulbs. a. Construct a box and whisker plot of these data. On this basis, draw a conclusion concerning the distribution of the population from which this sample was drawn. O A OB O c. O D.

An oil company wished to verify the viscosity of its premium 35-weight oil. A simple random sample of specimens taken from automobiles running at normal temperatures was obtained. The viscosities observed are shown below. Determine if the median viscosity at normal running temperatures is equal to 35 as advertised for the company's premium 35-weight oil. (Use a = 0.05.)
