Answer:

\bar x = 3.545

Median = 3.435

Step-by-step explanation:

Given

x:3.89, 3.51, 3.97, 3.31, 3.21, 3.36, 3.67, 3.24, 3.27

10th: 4.02

Solving (a): The mean

This is calculated as:

\bar x = \frac{\sum x}{n}

So, we have:

\bar x = \frac{3.89 +3.51 +3.97 +3.31 +3.21 +3.36 +3.67 +3.24 +3.27+4.02}{10}

\bar x = \frac{35.45}{10}

\bar x = 3.545

Solving (b): The median

First, we sort the data; as follows:

3.21, 3.24, 3.27, 3.31, 3.36, 3.51, 3.67, 3.89, 3.97, 4.02

n = 10

So, the median position is:

Median = \frac{n + 1}{2}th

Median = \frac{10 + 1}{2}th

Median = \frac{11}{2}th

Median = 5.5th

This means that the median is the average of the 5th and 6th item

Median = \frac{3.36 + 3.51}{2}

Median = \frac{6.87}{2}

Median = 3.435
