Question

problems. what is the mean time for each problem? make a

Explanation:

Step1: Count the number of data points

For time 24: 4 points, time 25: 4 points, time 27: 2 points. So total data points: \(4 + 4 + 2=10\)

Step2: Calculate the sum of all data

Sum = \(24\times4 + 25\times4 + 27\times2\)
\(=96 + 100 + 54\)
\(=250\)

Step3: Calculate the mean

Mean = \(\frac{250}{10}=25\)

Answer:

25
