Question

Consider the folic wing data set that consists of 10 point, {0.0, 1, 3, 7, 10, 15, 22, 48, 50}, how many of them would he considered outliers? 0 1 2 3 4 Consider the following data set, {-l, 0, 2,1. -2). and these statements regarding this data set. The sample mean is equal to the sample median The sample standard deviation is less than 1.7 The range is 4. Which of these statements are true? They are all true Only (i) and (Iii) are true Only (ii) and (iii) are true Only (i) is true Only (iii) is true

Explanation / Answer

5.

There are 10 points. Hence,

Q1 = median of lower half = 1
Q3 = median of upper half = 22

Hence,

IQR = 22 - 1 = 21

Hence,

Q1 - 1.5IQR = -30.5
Q3 + 1.5IQR = 53.5

As all entries are between these two values (-30.5 and 53.5), then there are no outliers,

OPTION A: 0 [ANSWER]
