Question

the length (in words) of seven articles from a particular newspaper are listed below. find the mean, median, and mode of the data, if possible. if any of these measures cannot be found or a measure does not represent the center of the data, explain why. 1276 1372 1156 1124 1229 1273 819

find the mean - word count. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

a. the mean word count is
(round to one decimal place as needed.)

b. there is no mean word count.

Explanation:

Step1: Recall mean formula

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are the data - points and $n$ is the number of data - points. Here, $n = 7$ and the data points are $x_1=1276$, $x_2 = 1372$, $x_3=1156$, $x_4 = 1124$, $x_5=1229$, $x_6=1273$, $x_7 = 819$.

Step2: Calculate the sum of data - points

$\sum_{i = 1}^{7}x_{i}=1276 + 1372+1156+1124+1229+1273+819=7249$.

Step3: Calculate the mean

$\bar{x}=\frac{7249}{7}\approx1035.6$.

Answer:

A. The mean word count is $1035.6$
