Question

find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question. listed below are foot lengths in inches of randomly selected women in a study of a countrys military in 1988. are the statistics representative of the current population of all women in that countrys military? 9.0 8.6 10.4 8.6 10.3 9.3 9.4 9.8 10.1 10.4 10.4 a. find the mean. the mean is □ inch(es). (type an integer or a decimal rounded to two decimal places as needed.)

Explanation:

Step1: Calculate sum of data

$9.0 + 8.6+10.4 + 8.6+10.3+9.3+9.4+9.8+10.1+10.4+10.4 = 106.3$

Step2: Determine number of data points

There are $n = 11$ data - points.

Step3: Calculate the mean

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}=\frac{106.3}{11}\approx9.66$

Answer:

$9.66$
