Question

If the outliers are not included in the data set below, what is the mean of the data set?

Answer 1

Answer:

(C) 49

Step-by-step explanation:

The given data is:

42, 43, 46, 48, 57, 60, 96, 59, 38, 68, 29

An outlier is an observation which is quite different or far away from the rest of the data set values, therefore in the given data set, 96 is an outlier as 96 is very far away from the rest of the data set values.

Now, excluding 96, mean is given as:

$Mean=\frac{42+43+46+48+57+60+59+38+68+29}{10}$

$Mean=\frac{490}{10}$

$Mean=49$

therefore, the mean of the given data set values is 49.

Hence, option C is correct.

Answer 2

49 is the answer. Hope it helps!
