Agency leadership decides to run a One Sample-T hypothesis test to determine if the mean vehicle weight of all passenger vehicles currently on the road is significantly different than 2600 pounds. Assume that all necessary Central Limit Theorem conditions for a One-Sample T-test have been met.

Part 2

What is the appropriate null hypothesis in this case?

The mean vehicle weight of all passenger vehicles currently on the road is

equal to

not equal to

greater than

less than

2600 pounds.

Part 3

What is the appropriate alternative hypothesis in this case?

The mean vehicle weight of all passenger vehicles currently on the road is

not equal to

greater than

equal to

less than

2600 pounds.

Part 4

What is the test statistic for this hypothesis test?

The test statistic is enter your response here

.

(Round to two decimal places as needed.)

Part 5

What is the p-value for this hypothesis test?

The p-value is enter your response here

.

(Round to three decimal places as needed.)

Part 6

What would you conclude based on an =0.05 level?

We

reject

fail to reject

the null hypothesis and

do not accept

accept

the alternative hypothesis since there

is not

is

sufficient evidence that the mean vehicle weight of all passenger vehicles currently on the road is

not equal to

equal to

2600 pounds due to the p-value being

greater

less

than the level.

Part 7

Based upon your hypothesis test, was the observed outcome unusual? If so, how unusual was the outcome?
