James works in a factory producing cookies. The number of chocolate chips in a cookie have a Poisson distribution with parameter A. James would like to test whether the average number of chocolate ch...
QUESTION 13 A sample of 16 cookies is taken to test the claim that each cookie contains at least 9 chocolate chips. The average number of chocolate chips per cookie in the sample was 7.875. The standard deviation of the population is 2. Assume the distribution of the population is normal. Let u denote the average number of chocolate chips in all the cookies. The hypothesis to test the claim is: H: 129 Hu<9 The p-value for the test statistics...
photos for each question are all in a row (1 point) In the following questions, use the normal distribution to find a confidence interval for a difference in proportions pu - P2 given the relevant sample results. Give the best point estimate for p. - P2, the margin of error, and the confidence interval. Assume the results come from random samples. Give your answers to 4 decimal places. 300. Use 1. A 80% interval for pı - P2 given that...
