The lengths of the reigns of 50 British monarchs (in years) are summarized with a five-number summary as follows: xmin = 0, Q1 = 6, = 15.5, Q3 = 24, xmax = 63, = 18.92. If the maximum of 63 years is accidentally recorded as 630 years, how will this affect the median?

The median will increase. The median will decrease. The median will be unchanged. It is impossible to determine without having the complete data. 10. As part of a new physical fitness program, the Crooked Oak Middle School in Oklahoma City, Oklahoma, records the number of sit-ups each sixth-grade student can do in one minute. A random sample for males and females was obtained and the given box plots were drawn. Identify the correct statement about the similarities and differences of the two distribution. a.Both distributions are centered near 29 and are similar in variability, but they differ in skewness. b.Both distributions are centered near 29 and are positively skewed, but they differ in variability. c.Both distributions are positively skewed and are similar in variability, but they are centered near different values

Solution

7) Since Extreme values (outliers) do not affect the median, So option c) is correct

10) From the box plot it is clear that

option b.Both distributions are centered near 29 and are positively skewed, but they differ in variability. is correct

As males box plot is more dispersed then girls
