Inorder to ensure the success of the evening, they've asked a random sample of 53 patrons whether theywould come to the showing or not. Of the 53 patrons, 15 said that they would come to see the film.Construct a 98% confidence interval to determine the true proportion of all patrons who would beinterested in attending the showing.a) What is the point estimate for the true proportion of interested patrons? (please input a proportionaccurate to four decimal places)b) Complete the interpretation of the confidence interval. Please provide the bounds for the confidenceinterval in decimal form, accurate to four decimal places, and list the lower bound first."We are% confident that the true proportion of patrons interested in attendingthe showing of Puppet Master is betweenandc) The theater is only willing to show Puppet Master if they are confident that at least 40% of their patronswould be interested in seeing the film. Should they show it??

The random variable interested patrons follows normal distribution. We have to construct 98%…
