3. Alpha Airlines claims that only 15% of its flights arrive more than 10 minutes late. Let p be the proportion of all of Alpha’s flights that arrive more than 10 minutes late. Suppose we take a random sample of 50 flights by Alpha Airlines.and we found that there are 5 flights which arrived more than 10 minutes late. a. construct a 90% confidence interval for the proportion of all of Alpha’s flights that arrive more than 10 minutes late. b. Test at the 2% significance level whether the Alpha Airlines’s claim is true

7. A company that has many department stores in the southern states wanted to find at two such stores the percentage of sales for which at least one of the items was returned. A sample of 800 sales randomly selected from Store A showed that for 280 of them at least one item was returned. Another sample of 900 sales randomly selected from Store B showed that for 279 of them at least one item was returned. a. Construct a 98% confidence interval for the difference between the proportions of all sales at the two stores for which at least one item is returned. b. Using the 10% significance level, can you conclude that the proportions of all sales for which at least one item is returned is higher for Store A than for Store B?
Suppose Devonna owns a national chain of day care centers. She believes that 62% of her students have been to the beach in the last year. She samples 152 children who are enrolled in her 15 day care centers in the state of Florida and finds out that 48 have been to the beach in the last year. From this data, she calculates the z-statistic. Next, she wants to calculate the z-confidence interval for the proportion. Indicate whether or not the requirements for the z-confidence interval for a proportion have been met, and select the reason or reasons why the requirements have or have not been met. The requirements have not have been met because the sample is not random. the sample is random. the setting is not binomial. there are not at least 10 successes and 10 failures. there are at least 10 successes and 10 failures. the setting is binomial.
