Problem 10BSC

In Exercises, find the range, variance, and standard deviation for the given samph data. Include appropriate units (such as “minutes”) in your results. (The same data were used in Section 3-2 where we found measures of center. Here we find measures of variation.) Then answer the given questions.

Florida Manatee Deaths Listed below are the numbers of manatee deaths caused each year by collisions with watercraft. Manatees, also called “sea cows, “ are large mammals that live underwater, often in or near waterways. The data are listed in order for each year of the past decade.

Step 1 of 5</p>

From the given information, the numbers of manatee deaths caused each year by collisions with watercraft are

Step 2 of 5</p>

From the given information, maximum data value is 97 and minimum value is 69. We know that range of the given set of sample values found as follows:

Therefore, the range of the given set of observations is 28.

Step 3 of 5</p>

From the given information,. We know that variance of given set of sample value found as follows:

Therefore, the variance of the given sample is 101.12.
