A local concert center reports that it has been experiencing a 15% rate of no-shows on advanced reservations. Among 150 advanced reservations, find the probability that there will be no more than 19 no-shows. Apply normal distribution to the binomial probability distribution. Round the standard deviation to three decimal places to work the problem.

The mean of a normal probability distribution is 120 the standard deviation is 10. About what percent of the observations lie between 110 and 130

The weights of newborn baby boys born at a local hospital are believed to have a normal distribution with a mean weight of 3811 grams and a standard deviation of 442 grams. If a newborn baby boy born at the local hospital is randomly selected, find the probability that the weight will be between 3590 and 4429 grams. Round your answer to four decimal places.

The NJ Department of Health has reported the average life span of NJ residents is 81 years. If the standard deviation is σ = 4 years, what is the probability of a person living to at least 92 years of age?

Trucks in a delivery fleet travel a mean of 8080 miles per day with a standard deviation of 3737 miles per day. The mileage per day is distributed normally. Find the probability that a truck drives less than 150150 miles in a day. Round your answer to four decimal places.

The time spent waiting in the line is approximately normally distributed. The mean waiting time is 6 minutes and the standard deviation of the waiting time is 2 minutes. Find the probability that a person will wait for more than 7 minutes. Round your answer to four decimal places
