The following three histograms represent the probability distributions of the three random variables X, Y, and Z.Which of the three random variables has the largest standard deviation? X Y Z All three random variables have the same standard deviation.

Three random variables, U, V, W have distributions as shown in the graphs below.Which one of the three random variables has the largest standard deviation? U V W All three random variables have the same standard deviation.

The graph below represents stocks, labeled A , B , and C , on the same axis. Determine which normal distribution has the largest standard deviation.A figure consists of three curves along a horizontal axis, labeled Upper A, Upper B and Upper C. Curve Upper A is farthest to the right, curve Upper B is tall and skinny, and curve Upper C is farthest to the left.Select the correct answer below:A B C

The random variable X, representing the number of items sold in a week, has the following probability distribution:Which of the three random variables has the smallest standard deviation? X Y Z All three random variables have the same standard deviation.

Assume that the average rating in each of the three classes is 5 (which should be visually reasonably clear from the histograms), and recall the interpretation of the SD as a "typical" or "average" distance between the data points and their mean. Judging from the table and the histograms, which class would have the largest standard deviation, and which one would have the smallest standard deviation? Explain your reasoning.

A distribution whose histogram has one main peak is called ______________ , two peaks: ______________ , three or more: _______________ .unimodal, bimodal, multimodalunimodal, duomodal, triomodalonemodal, bimodal, triomodalunimodal, duomodal, multimodal
