The ETA reported that the U.S mean unemployment insurance benefit was $238 per week. A researcher in Virginia anticipated that sample data would show evidence that the mean weekly unemployment insurance benefit in Virginia was below the national average.
a. Develop the null and alternative hypotheses that could be used to support the researchers claim.
b. What is the Type I error in this situation?
c. What is the Type II error in this situation?
Homework Answers
(a) H0 : mu = $238
H1 : mu < $238
(b) Type I Error : Reject H0 when H0 is true.
It is concluded that the mean weekly unemployment insurance benefit in Virginia is less than $238 but actually the mean is $238
(c) Type II Error : Fail to Reject H0 when H0 is false.
It is concluded that the mean weekly unemployment insurance benefit in Virginia is $238 but actually the mean is less than $238.

It is believed that the average amount of money spent per U.S. household per week on food is about $96, with standard deviation $9. A random sample of 49 households in a certain affluent community yields a mean weekly food budget of $100. We want to test the hypothesis that the mean weekly food budget for all households in this community is higher than the national average. State the null and alternative hypotheses for this test, the test statistic and...

The U.S. Department of Agriculture reports that the mean cost of
raising a child from birth to age 2 in rural areas is $8390. For a
specific rural area, a random sample of 900 children (age 2) has a
mean cost of $8275. The p -value for this sample is .108.
Does this indicate that the mean cost in this area is less than the
national average?
Claim: The mean cost of raising a child from birth to age...
