Question

At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 46 minutes and a standard deviation of 3 minutes. If you visit that restaurant 29 times this year, what is the expected number of times that you would expect to wait between 39 minutes and 53 minutes, to the nearest whole number?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

35 36 CetaceaNow is a conservationist organization that monitors the health of whale and dolphin populations worldwide. As part of their work, they are modelling the lengths of blue whale calves that will be born over the next decade. For their model, CetaceaNow is using a normal distribution with a mean of 277 in and a standard deviation of 40 in. Use this table or the ALEKS calculator to find the percentage of blue whale calves with a length of between 203 in and 251 in according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%). % Submit Assignmer Continue
