Use the histograms shown to answer the question Is either hi

Use the histograms shown to answer the question. Is either histogram symmetric? A) The second is symmetric, but the first is not symmetric. B) Neither is symmetric. C) The first is symmetric, but the second is not symmetric. D) Both are symmetric. Compute the range for the set of data. 9, 20, 9, 20, 9, 20, 9, 20 A) 11 b) 20 c) 14.5 D) 22 Provide an appropriate response. A random sample of sale prices of homes yielded the following summary information: MIN $41, 000 25%: $82, 000 Median: $124, 000 MAX $276, 000 75%: $169, 000 Comment on a home that had a sale price of $429, 000. A) This sale price falls between the lower and upper fences. It can be considered a potential outlier. B) This value falls outside of the third quartile, but cannot be considered an outlier. C) This sale price would be expected since it falls inside the lower and upper fences. D) This value falls outside the upper fence and is considered an outlier. In interpreting a boxplot of a data set we note that the median is to the left of the center of the and the right line is longer than the left line. We can conclude that A) The data is skewed right. B) The data is symmetric. C) Skewness or symmetry cannot be determined by a box plot. D) The data is skewed left.

Solution

31. B. Neither is symmetric.

32. Given 9,20,9,20,9,20,9,20

Range= highest value - lowest value

=20-9

= 11

34. C skewness or symmetry cannot be determined by a box plot.
