The time it takes for a Madonna concert to sell out follows a normal distribution with an average sell out time of 80 minutes with a standard deviation of 15 minutes.
Fill in the values for the normal curve for the time to sell out. From left to right, the values would be:
b.) Quantity, what percent of shows would they expect to sell out in 50 minutes or less?
c) How many shows out of the 50 would be expected to take 95 minutes or more to sell out? Show how you arrive at your value.

1. The time it takes a symphony orchestra to play Beethoven's Ninth Symphony has a normal distribution with a mean of 64.3 minutes and a standard deviation of 1.15 minutes. If an orchestra plays it so slowly that 80% of the orchestras play faster than the orchestra, how long does the orchestra play?

The length of time it takes college students to find a parking spot in the library parking lot follows anormal distribution with a mean of 5.5 minutes and a standard deviation of 1 minute. Find theprobability that a randomly selected college student will take between 4.0 and 6.5 minutes to find aparking spot in the library lot.
The length of time it takes college students to find a parking spot in the library parking lot follows a normal distribution with a mean of 4.0 minutes and a standard deviation of 1 minute. Find the probability that a randomly selected college student will take between 2.5 and 5.0 minutes to find a parking spot in the library lot.
a. Time to finish a quiz in minutes follows a normal distribution with mean 6 and standard deviation .7. A student took 4.8 minutes. What is this student’s z-score? b. Time to finish a quiz in minutes follows a normal distribution with mean 6 and standard deviation .7. What proportion of students complete the quiz in less than 5.2 minutes? Use the normalcdf command on your calculator with 6 as the mean, .7 as the standard deviation, a very large negative...
Assume the commute time is a random variable that follows the normal distribution with a mean of 10.3 minutes with a standard deviation of 4.8 minutes. You wish to calculate the probability that the commute time is more than 16.3 minutes. What is the z value you would look up in the standard normal table to answer this question? What is the probability that the commute time is more than 16.3 minutes? What would be the targeted average commute time...
The waiting time for patients at local walk-in health clinic follows a normal distribution with a mean of 15 minutes and a population standard deviation of 5 minutes. The quality-assurance department found in a sample of 64 patients that the mean waiting time was 13.5 minutes. Using the 99% confidence level and the 95% confidence interval, is it reasonable to conclude the sample mean waiting time is statistically significantly different from the population mean waiting time? i. Firstly, what are...
The average time taken to complete an exam, X, follows a normal probability distribution with mean = 60 minutes and standard deviation 30 minutes. What is the probability that a randomly chosen student will take more than 45 minutes to complete the exam?
