When iPhone was first released in 2007, Google Maps was the default mapping software that was included in Apple’s mobile operating system. In September 2012, Apple released an upgraded operating system for the iPhone which replaced Google Maps with its own newly developed Apple Maps. Unfortunately, Apple Maps was plagued with many mapping errors and did not contain all of the features found in Google Maps. In a December 2012 survey of iPhone users, 45% of the respondents said that they “ hated Apple Maps.” Using the binomial tables, answer the following questions based on a random sample of 20 iPhone users:
a. What is the probability that 12 iPhone users from this sample hated Apple Maps?
b. What is the probability that more than 12 iPhone users from this sample hated Apple Maps?
c. What is the probability that less than 10 iPhone users from this sample hated Apple Maps?
d. What are the mean and standard deviation for this distribution?
e. Construct a histogram for this distribution.
