1). The average (arithmetic mean) of 7 different numbers is 5
Consider the following two quantities:
A. The median of the 7 numbers. B. 5.
A. Quantity A is greater than Quantity B
B. Quantity B is greater than Quantity A
C. The two quantities are equal.
D. The relationship cannot be determined without more information.
2). List S = {16, 9, 23, X, 13, 16}
In list S, the mean and median are equal to one another. What is the value of X?
Homework Answers
1)
D. The relationship cannot be determined without more information.
2)
for sum of all values =77+x
as 16 falls apprximately in midddle if we put all values in ascending order ; therefore it should be median
hence x+77=6*16
x =96-77 =19

The average house has 14 paintings on its walls. Is the mean
different for houses owned by teachers? The data show the results
of a survey of 13 teachers who were asked how many paintings they
have in their houses. Assume that the distribution of the
population is normal.
