The number of emergency calls a local police department receives per 24-hour period is distributed as shown here. Construct a graph for the data. At a small rural airport, the number of arrivals per hour during the day has the distribution shown. Find the mean, variance, and standard deviation for the data. Between z = 1.05 and z = 1.78 Find the area under the standard normal distribution curve. To the right of z = – 0.17 Find the area under the standard normal distribution curve. P (z < – 1.77) Find the probabilities for each, using the standard normal distribution.Post your question
