DISCUSSION QUESTIONS AND PROBLEMS2-44 Using the data in Problem 2-43, determine the prob-ability of more than 3 visits for emergency room ser-vice on any given day.79 :2-43 Patients arrive at the emergency room of CostaValley Hospital at an average of 5 per day. The de-mand for emergency room treatment at Costa Valleyfollows a Poisson distribution.(a) Using Appendix C, compute the probability ofexactly 0, 1, 2, 3, 4, and 5 arrivals per day.(b) What is the sum of these probabilities, and whyis the number less than 1?

Given that X~Poisson (λ) Average =λ=5

Consider two data sets. Set A: n = 5; x = 4 Set B: n = 50; x = 4 (a) Suppose the number 26 is included as an additional data value in Set A. Compute x for the new data set. Hint: x = nx. To compute x for the new data set, add 26 to x of the original data set and divide by 6. (Round your answer to two decimal places.) (b) Suppose the number 26 is included as an additional data value in Set B. Compute x for the new data set. (Round your answer to two decimal places.)
2. Problem 3, page 455. Checkout time at a supermarket is monitored using a mean and range chart. Six samples of n=20 observation have been obtained and the sample means and ranges computed: Sample Mean Range Sample Mean Range 1 3.06 0.42 4 3.13 0.46 2 3.15 0.5 3.06 0.46 3 3.11 0.41 3.09 0.45 a. Using the factors in the table, determine UCL and LCL for mean & range chart. b. Is the process under control? c. (Not in the book) If a new sample is collected and the mean is 3.02 and the range is 0.5. Is the process under control?

Problem 7.On our final attempt, we divide the neighborhoods into two categories: "mostly white" White50) and "mostly minority" (White < 50). Here is a summary of the data: sd(Schools) Number of Neighborhoods 70 Mean(Schools) Group 725.53 826.06 Mostly Minority Mostly White 34 54.60 68.77 A. Using a two-sample t test, test the claim that there is no difference in school performance between mostly minority and mostly white neighborhoods. Use a significance level of 1%. B. Name one assumption necessary for the two-sample t test that is violated in this analysis. Justify why the assumption does not hold.
