1. There are 10 employees in a particular division of a company. Their salaries have a mean of
$70,000, a median of $55,000, and a standard de- viation of $60,000. The largest number on the list is $100,000. By accident, this number is changed to $1,000,000.
a. What is the value of the mean after the change?
b. What is the value of the median after the change?
c. What is the value of the standard deviation after the change?
2. Quartiles divide a sample into four nearly equal pieces. In general, a sample of size n can be broken into k nearly equal pieces by using the cutpoints (i/ k)(n +1)
for i = 1,..., k - 1. Consider the following ordered
sample:
2 18 23 41 44 46 49 61
62 74 76 79 82 89 92 95
a. Tertiles divide a sample into thirds. Find the tertiles of this sample.
b. Quintiles divide a sample into fifths. Find the quintiles of this sample.

How should bogaert analyze these data
: With older biological brothers the probability of homosexuality increased from 3% to around 5%, but there was no similar increase with older stepbrothers or with biological sisters or stepsisters. How should Bogaert analyze these data?

What is the appropriate analysis of these data
: The authors actually broke the data into seven different times of day, but for purposes of this example assume that the dependent variable is each participant's mean SSS score over the 30-day period. What is the appropriate analysis of these data?
