A student who has a 9 am class on Monday, Wednesday and Friday mornings wants to know if the mean time taken by students to find parking spaces just before 9 am is the same for each of these three days of the week. He randomly selects five weeks and records the time taken to find a parking space on Monday, Wednesday and Friday of each of these five weeks. These times (in minutes) are given in the following table. Assume that this student is representative of all students who need to find a parking space just before 9 am on these three days. Monday Wednesday Friday
6 9 3
12 12 2
15 5 10
14 14 7
10 13 5
At the 5% significance level, test the null hypothesis that the mean time taken to find a parking space just before 9 am on Monday, Wednesday and Friday is the same for all students.

$36.40

Step-by-step explanation

16 ounces in 1 pound

0.65 x 16 = $10.40

Peanuts

0.65 x 8 = $5.2 (you do this to get the extra 8 ounces)

$10.40 + $5.2 = $15.6

Pecans

$10.40 + $10.40 = 20.8

Total

$15.6 + 20.8 = $36.40
