Answer to Problem 24E
The mean is 7.62cm and the median is 0.254cm
Explanation of Solution
Given:
Each of C’s measurement is 0.2 inches large.
Mean = 3.2 inches
Standard deviation = 0.1 inches
Calculation:
The diameter of each tennis ball in a bag was measured with a standard ruler and obtained a mean of
To get a correct measurement in centimeters, it is needed to subtract the 0.2 inches from the mean value and then transform the same measurement to centimeters. Thus the new mean diameter of each tennis ball is calculated as follows:
The change in location does not affect the standard deviation so the standard deviation remains same and convert the same measurement to centimeters. Thus the new standard deviation of diameter for each tennis ball is calculated as follows:
Conclusion:
Therefore, the mean is 7.62cm and the median is 0.254cm
