c. Do you think that the assumption needed in order to construct the confidence interval estimate in (a) is valid? Explain A Yes, the data suggest the population distrbution approximately follows the I distribution 8. No, the data suggest the population distribution is skewed to the right C. Yes, the data suggest the population distribution is approximately normal. O D. No, the data suggest the population distribution skewed to the left

Question
i need the answer quickly
A large family-held department store had the business objective of improving its response to complaints The variatle of interest was defined as the nm between when the complaint was made and when it was resolved Data were collected from 40 complaints that were made in the last year Use the dat (a) through (d) below I Click the icon to view the data table a Construct a 95% confidence interval estimate for the population mean number of days between the receipt of a complaint and the resolution of the or The 95% confdence interval estimate is from 28.4 days to 53.1 days (Round to one decimal place as needed.) b. What assumption must you make about the population distribution in order to construct the confidence interval estimate in (a)? A The number of days to resolve complaints follows the I distribution OB The number of complaints per day follows the t distribution C The number of complainte per day is normally distributed D The number of days to resolve complaints is normally distributed. c. Do you thinik that the assumption needed in order to construct the confidence interval estimate in (a) is valid? Explain O A Yes, the data suggest the population distnbution approximately follows the I distribution. O B. No, the data suggest the population distribution is skewed to the right OC. Yes, the data suggest the population distribution is approximately normal. O D. No, the data suggest the population distribution is skewed to the left Complaint Data Days Between Complaint and Resolution of Complaint 7 24 20 19 26 93 10 64 45 162 32 28 24 33 69 16 18 1 34 115 17 7 64 2 27 111 8 45 152 16 26 26 37 12 26 14 81 49 42 29
