Consider the probability that at least 36 out of 298 cell phone calls will be disconnected. Choose the best description of the area under the normal curve that would be used to approximate binomial probability.

The option are

Area to the right of 35.5

Area to the right of 36.5

Area to the left of 35.5

Area to the left of 36.5

Area between 35.5 and 36.5

Solutions

Expert Solution

Option-A) Area to the right of 35.5. Because P(X > 36) = P(X > 35.5) after continuity correction

A problem with a cell phone that prevents a customer from receiving calls is upsetting both customers and the telecommunications company. The file Phone contains samples of 20 problems reported to two different offices of the telecommunication company and the time to clear these problems (in minutes) from the customers’ phones. Is there evidence that addressing this phone issue results in different mean waiting times at the two offices? (Use a 0.05 level of significance) I WANT THE ANSWER IN...

According to a Virginia Tech survey, college students make an average of 11 cell phone calls per day. Moreover, 80% of the students surveyed indicated that their parents pay their cell phone expenses (J. Elliot, “Professor Researches Cell Phone Usage Among Students,” www.physorg.com, February 26, 2007). 1. If you select a student at random, what is the probability that he or she makes more than 10 calls in a day? More than 15? More than 20? 2. If you select...
