It is reported in USA Today that the average flight cost
nationwide is $368.88. You have never paid close to that amount and
you want to perform a hypothesis test that the true average is
actually less than $368.88. What are the appropriate hypotheses for
this test?
Question 1 options:
|
1)
|
HO: μ ≤ 368.88
HA: μ > 368.88 |
|
|
2)
|
HO: μ > 368.88
HA: μ ≤ 368.88 |
|
|
3)
|
HO: μ = 368.88
HA: μ ≠ 368.88 |
|
|
4)
|
HO: μ ≥ 368.88
HA: μ < 368.88 |
|
|
5)
|
HO: μ < 368.88
HA: μ ≥ 368.88 |

Suppose the national average dollar amount for an automobile
insurance claim is $618.255. You work for an agency in Michigan and
you are interested in whether or not the state average is different
from the national average. The hypotheses for this scenario are as
follows: Null Hypothesis: μ = 618.255, Alternative Hypothesis: μ ≠
618.255. A random sample of 55 claims shows an average amount of
$615.599 with a standard deviation of $72.2183. What is the test
statistic and p-value for this test?

In the year 2000, the average vehicle had a fuel economy of
20.01 MPG. You are curious as to whether the average in the present
day is less than the historical value. The hypotheses for this
scenario are as follows: Null Hypothesis: μ ≥ 20.01, Alternative
Hypothesis: μ < 20.01. A random sample of 31 vehicles shows an
average economy of 21.06 MPG with a standard deviation of 5.384
MPG. What is the test statistic and p-value for this test?
