iOS Marketshare You plan to develop a new iOS social gaming app that you believe will surpass the success of Angry Birds and Facebook combined. In forecasting revenue, you need to estimate the percentage of all smartphone and tablet devices that use the iOS operating system versus Android and other operating systems. How many smartphones and tablets must be surveyed in order to be 99% confident that your estimate is in error by no more than two percentage points? a. Assume that nothing is known about the percentage of portable devices using the iOS operating system. b. Assume that a recent survey suggests that about 43% of smartphone and tablets are using the iOS operating system (based on data from NetMarketShare). c.

CURSED MOVIE Released in 1956, the movie The Conqueror attracted considerable attention because many members of the cast and crew died from cancer supposedly resulting from exposure to radioactive fallout. The movie was shot a short distance from a site in Nevada where above-ground tests of atomic weapons were conducted. Among the 220 cast and crew members, 91 developed cancer. According to the National Cancer Institute, for that time period and for the age cohort, the incidence of cancer was about 40%. Use a 0.05 significance level to test the claim that the sample of cast and crew members is from a population in which the rate of cancer is greater than 40%. What do you conclude about the movie being a curse? Find null hypothesis and alternative hypothesis. Find test statsistic. Find P-value. How do you find p hat
