Answer:
The test is not significant at 5% level of significance, hence we conclude that there's no variation among the discussion sections.
Step-by-step explanation:
Assumptions:
1. The sampling from the different discussion sections was independent and random.
2. The populations are normal with means and constant variance
There's no variation among the discussion sections

Since our p-value is greater than our level of significance (0.05), we do not reject the null hypothesis and conclude that there's no significant variation among the eight discussion sections.
Answer:
12000-14000 (in miles)
Step-by-step explanation:
We are given that the annual cost of driving a certain car is given by the formula
Where m=Represents the number of miles driven per year
C=Cost in dollars
We have to find the range of miles that Jane can drive her new car.
Range of budgets=$7040-$7780
Substitute C=$7040 in the given formula
Substitute C=$7780 in the given formula
The range of miles that Jane can drive her new car=12000-14000
