Determine whether the following graph can represent a variable with a normal distribution. Explain your reasoning. If the graph appears to represent a normal distribution, estimate the mean and standard deviation. 5 10 15 20 25 30 35 x

The following graph shows that the normal distribution A has greater variability than the normal distribution B. True or false

Write True or False for the statement. If the statement is False, correct the statement. You are shown the following normal probability plot where the data set percentiles are on the y-axis. The sample size is n = 1,000. The data set can best be described as skewed to the left. Normal Q-Q Plot 2 -3

Use a calculator or computer software to generate a normal quantile plot for the data in the accompanying table. Then determine whether the data come from a normally distributed population.

Choose the correct answer below. OA. The distribution is not normal. The points are not reasonably close to a straight line. OB. The distribution is normal. The points show a systematic pattern that is not a straight-line pattern. OC. The distribution is normal. The points are not reasonably close to a straight line and do not show…
