Suppose the number of dropped footballs for a wide receiver, over the course of a season, are normally distributed with a mean of 16 and a standard deviation of 2. what is the z-score for a wide receiver who dropped 13 footballs over the course of a season? −3 −1.5 1.5 3

the z-score for a wide receiver who dropped 13 footballs over the course of a season is:

                                -1.5

The z-score is a measurement of relationship between the score and the mean of group of scores.

The formula to find the z-score is given by:

where m represent the mean score and σdenote the standard deviation.

and x is the score whose z-score is to be calculated.

Hence, here we have:

m=16 , σ=2 and x=13

Hence, the z-score is calculated as:

       Hence, the required z-score is:

                      -1.5
