Extracted text: Consider 3 rocket launchings at this NASA base. Let X-number of launchings among 3 that are delayed dus 7. Experience has shown that 30% of rocket launchings at a NASA base have had to be delayed due to wet conditions. a) X has a binomial distribution with n= 9. Use the following data to 825 700 elayed d and = Monthly Rent Size (Sq Ft) 0) Find the probability that exactly 0 of 3 launchings will have to be delayed due to weather conditions. Predict th a. c) Find the mean number of rocket launchings that will be delayed among 3 8.. A movie theater is interested in the proportion of Columbia Pictures films that are R-rated. A random sample of 65 films are considered, of which 28 are R-rated. a) Compute a 95% confidence interval for the proportion of all Columbia pictures that are R-rated. a Interpret the 95% confidence interval from a) in the context of the problem.
