Question

an advertisement for a speed - reading course claimed that the \average\ reading speed for people completing the course was 1000 words per minute. shown below are the actual data for the reading speeds per minute for a sample of 24 people who completed the course. complete parts (a) through (c) below
1000 900 600 1000 900 750
650 1000 1050 800 1000 850
700 750 800 950 900 950
600 1100 950 700 750 650
a. find the mean, median, mode, and midrange
what is the mean? choose the correct answer below, and, if necessary fill in the answer box to complete your choice
○ a. the mean is (round to the nearest whole number as needed)
○ b. there is no mean

Explanation:

Step1: Sum up all data

First, sum up all the reading - speed data:

$$
LATEXBLOCK0
$$

Step2: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), where \(n = 24\) (the number of data points) and \(\sum_{i=1}^{n}x_{i}=22050\).

$$ \bar{x}=\frac{22050}{24}=918.75\approx919 $$

Answer:

A. The mean is \(919\)
