Question

the following pulse rates were recorded for a group of 15 students. the mean pulse rate is 73. how many pulse rates were higher than the mean? 65, 64, 87, 78, 80, 62, 85, 87, 66, 69, 70, 78, 62, 62, 80 how many pulse rates were higher than the mean?

Explanation:

Step1: Identify the mean

The mean pulse rate is given as \(73\).

Step2: Count the values greater than the mean

Go through the list \(65, 64, 87, 78, 80, 62, 85, 87, 66, 69, 70, 78, 62, 62, 80\) and check each value:

• \(87>73\)
• \(78>73\)
• \(80>73\)
• \(85>73\)
• \(87>73\)
• \(78>73\)
• \(80>73\)

Count these values.

Answer:

\(7\)
