On a typical day at a local popular mall, the number of shoplifters caught by mall security fluctuates from day to day, with an average of 7.6 caught per day. Suppose you are to count the number of shoplifters apprehended at this mall today. (Assume today is a typical day at the mall.) Part (a) Compute the probability that mall security apprehended 10 shoplifters. (use four decimals in your answer) Part (b) Compute the probability that mall security will apprehend at least 6 shoplifters. Enter your answer to four decimals. Part (c) Compute the probability that between 6 and 11 (inclusive) shoplifters will be apprehended. Enter your answer to four decimals. 0 obonds on a typical day. What can you say about this 4

Question
Transcribed Image Text:Part (d) Think about the distribution of the number of shoplifters mall security apprehends on a typical day. What can you say about this
distribution? Select the most appropriate reason below.
O A. The distribution of values is roughly symmetrical, with a mean of 7.6 shoplifters and a standard deviation of 2.75680975041804
shoplifters.
B. The number of shoplifters apprehended each day is 7.6.
C. The distribution of values is skewed to the right, with a mean of 7.6 shoplifters and a variance of 2.75680975041804 shoplifters.
D. The distribution of values is roughly symmetrical, with a mean of 7.6 shoplifters and a variance of 2.75680975041804 shoplifters².
E. The distribution of values is skewed to the right, with a mean of 7.6 shoplifters and a standard deviation of 2.75680975041804
shoplifters.
Part (e) On a typical day, the mall is open from 10:00am to 9:00pm, a total of 11 hours. You are interested in the number of shoplifters
apprehended in any given hour.
How many shoplifters would you expect mall security to catch in any given hour? Provide the variance of this count as well.
