Question

Consider the following data set that consists of 10 values: {0, 0, 1, 3, 7, 10, 15, 22, 48, 50}. Of these 10 values, how many of them would be considered outliers? Consider the following data set, {-1, 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 For Questions consider the following bivariate data: If a linear regression were fit to the data (and y is considered the response variable), what would be the fitted value of beta_1? If a linear regression were fit to the data, how many residuals would there be?

Explanation / Answer

8.

Here,

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

Hence,

IQR = Q3 - Q1 = 22 - 1 = 21

Hence, the upper and lower fences are

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

Values within these limits are acceptable. Hence, there are no outliers.

Therefore,

OPTION A: 0 [ANSWER]
