Suppose you are running an experiment investigating drivers’ response times
to a stop sign. Response time is defined at the time the driver puts
their foot on the break until the driver comes to a complete stop and is measured in seconds. The data is as
follows: 7, 8, 9, 6, 11, 9, 5, 12, 15, 10, 11, 6, 8, 8, 14. Plot a normal probability plot. Is the data normally distributed? Explain.
Homework Answers
To make the normal probability plot first we need to sort the data and then we need to find the area left to z-scores k /2n. Here k= 1, 3, 5, ...and n=15. Following table shows the same:
Now we need to plot data on x-axis and z-scores on y-axis. Following is the normal probability plot:
Since plot shows approximately straight line so we can say that the data normally distributed.

A researcher observed the behavior of drivers at a stop sign. She observed 25 cars between 6 and 7 am and 70 cars between 11 am and noon. In the early morning, only 8 of the 25 cars came to a full stop; in the late morning, she found 36 of the 70 cars came to a full stop. Complete the following table to reflect the information given above. Driver Behavior 6 am – 7 am (population #1) 11...

Suppose the time between buses at a particular stop is a positively skewed random variable with an average of 59 minutes and standard deviation of 6 minutes. Suppose the time between buses at this stop is measured for a randomly selected week, resulting in a random sample of n = 38 times. The average of this sample, X , is a random variable that comes from a specific probability distribution. (a)Which of the following is true about the distribution of...

You are running a physics experiment with n complicated steps that you must do in order, and students sign-up for some steps to help. Your experiment requires n steps, and each of the m students gives you a list of which steps they can help out with (steps require special skills). From experience, you know things run most smoothly when you have as little switching of shifts as possible. For example, if your experiment has <1, 2, 3, 4, 5,...
