spring 2015 math 117 p2 Item Binomial probability distribution table as prescribed What is the probability that in a sample of 12 people, that at most 5 people have health care insurance? What is the probability of one store at random having monthly sales between 140 and 155 ? In a random sample of 19 stores, what is the standard deviation of the sampling distribution? In a random sample of 10 stores, what is the probability that the average sales will be between 140 and 155? Mean of the 98.6% confidence Interval Error of the 98.6% confidence Interval Explain what this confidence interval means to someone who has no statistics background, and who has taken no statistics courses Has Health Care Insurance? <------- 1 = yes 0 = no 1 1 1 Based on this distribution, construct a binomial probability distribution table 1 for a sample of 14 people. Columns should include x, P(x) , cumulative P(x). 1 1 What is the probability that in a sample of 14 people, that at most 5 people have h
ealth care insurance? 1 1 0 1 0 1 1 1 0 1 0 Assume the monthly sales data in column A is normally distributed and represents the monthly sales at different stores. All figures are in $100,000. a. What is the probability of one store at random having monthly sales between 140 and 155 ? b. In a random sample of 19 stores, what is the standard deviation of the sampling distribution? c. In a random sample of 10 stores, what is the probability that the average sales will be between 140 and 155? Construct a 98.6% confidence interval around the mean monthly sales value. Mean of the confidence interval or Lower limit of confidence interval Error Upper limit of confidence Interval Explain what this confidence interval “means” to someone who has no statistics background, and who has taken no statistics courses If answer is not legible there will be no credit, and the answer must be in this yellow box.
