Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

Chapter 13.1, Problem 23STP
To determine

The statement that is true from the given 4 statements

Expert Solution & Answer
Check Mark

Answer to Problem 23STP

J. Both the mean and the median will increase.

Explanation of Solution

Given:

The given data is

  79,81,77,81,82,75,76

The temperature on 8th day is 80 degrees

Calculation:

Mean = Sum of all observations/Total number of observations

  =79+81+77+81+82+75+767=5517=78.714

Median = The exact middle value of the data when arranged from least to greatest

Order the data from least to greatest: 75, 76, 77, 79, 81, 81, 82

As, the total number of observations are 7 (odd), median will be the exact middle term.

Median = 79

Mode = The most frequent value in the given data set

So, Mode = 81

Now, we will calculate the new mean, median and mode by adding the temperature on the 8th day to the data set i.e. 80 degrees.

New data is: 79,81,77,81,82,75,76,80

New Mean = =79+81+77+81+82+75+76+808=6318=78.875

New Median:

Order the data from least to greatest: 75, 76, 77, 79, 80, 81, 81, 82

As, the total number of observations are 8 (even), median will be 4th term + 5th term/2.

So, Median = (79 + 80)/2

New Median = 79.5

New Mode = 81

Therefore, we can see that the mean and median both have increased.

Hence, the answer is J. Both the mean and the median will increase.
