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.)

1. A developmental psychologist would like to determine how much fine motor skill changes for children from age 3 to age 5. He takes a random sample of 9 three-year old children and gives each a manual dexterity test that measures fine motor skill. He tests these same children one and two years later, when they are each four- and five-years old. Higher scores on this test indicate better fine motor skills. Is there a significant difference in the motor skills at these ages? Test with an α = 0.01 and show ANOVA SPSS output.
