Question

Dallas Mavericks. From the ESPN website, in the Dallas Mavericks Roster, we obtained the following weights, in pounds, for the players on that basketball team for the $2013-2014$ season.

Use the technology of your choice to determine 

a. the population mean weight.

b. the population standard deviation of the weights. Note: Depending on the technology that you're using, you may need to refer to the formula derived in Exercise $3.220\left(a\right)$.

Step-by-Step Solution

Answer

Part $\left(a\right)$: The population mean value is, $\mu =169.33$.

Part $\left(b\right)$: The population standard deviation value is, $\sigma =4.45$.

Part a Step 1 . Given information

The given  weights, in pounds, for the players on that basketball team for the$2013-2014$ season. 

Part a Step 2 . The population mean of the given data is found by using Excel as follows,

From the above output, the population mean value is,$\mu =169.33$.

Part b Step 1 . The population standard deviation of the given data is found by using Excel as follows,

From the above output the population standard deviation value is, $\sigma =4.45$.
