Your reflection on the film should be 1-2 pages, double spaced. Follow standard formatting as listed in other writing assignments.This assignment will be given up to 25 points, based on quality and originality of your response.

 Find the indicated probability. Round the answer to 4 decimal places. (3pts) The participants in a TV quiz show are picked from a large pool of applicants with approximately equal numbers of men and women. Among the last 11 participants there have been only 2 women. If participants are picked randomly, what is the probability of getting at most 2 women when 11 people are selected?   

ON YOUR PAPER,  please confirm that you have read, understood and followed the exam instructions thoroughly.

Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution.The football coach randomly selected twelve players and timed how long each player took to perform a certain drill.
