A smart phone manufacturer is interested in constructing a 95% confidence interval for the proportion of smart phones that break before the warranty expires. 94 of the 1517 randomly selected smart phones broke before the warranty expired. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all smart phones that break before the warranty expires is between C] and C]. b. If many groups of 1517 randomly selected smart phones are selected, then a different confidence interval would be produced for each group. About C] percent of these confidence intervals will contain the true population proportion of all smart phones that break before the warranty expires and about C] percent will not contain the true population proportion . Hint: Hints L7!" Video E" [+] Assume that a sample is used to estimate a population proportion p. Find the 99.9% confidence interval for a sample of size 232 with 74% successes. Enter your answer as an open-interval (i.e., parentheses} using decimals (not percents) accurate to three decimal places
