The text discusses a problem involving the Poisson process in the context of a towing service.---The number of requests for assistance received by a towing service is modeled as a Poisson process with a rate of \( \alpha = 4 \) per hour.**(a)** Compute the probability that exactly eleven requests are received during a particular 5-hour period. (Round your answer to three decimal places.)*Response:* [Blank space with incorrect response indicator]**(b)** If the operators of the towing service take a 30-minute break for lunch, what is the probability that they do not miss any calls for assistance? (Round your answer to three decimal places.)*Response:* 0.135**(c)** How many calls would you expect during their break?*Response:* 2You may need to use the appropriate table in the Appendix of Tables to answer this question.---Note: The image does not contain any graphs or diagrams to explain.

Consider a data set containing the following values: 92 84 85 93 95 89 86 91 The mean of the preceding values is 89.375. The deviations from the mean have been calculated as follows: 2.625 –5.375 –4.375 3.625 5.625 –0.375 –3.375 1.625 If this is sample data, the sample variance is and the sample standard deviation is . If this is population data, the population variance is and the population standard deviation is . Suppose the largest value of 95 in the data was misrecorded as 93. If you were to recalculate the variance and standard deviation with the 93 instead of the 95, your new values for the variance and standard deviation would be .
Recall that Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Now suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer file. Let us say you took a random sample of n = 215 numerical entries from the file and r = 50 of the entries had a first nonzero digit of 1. Let p represent the population proportion of all numbers in the corporate file that have a first nonzero digit of 1.(i) Test the claim that p is less than 0.301. Use ? = 0.10.
