The average income of 10 families who reside in a large metropolitan East coast city is $62,456. The standard deviation is $9652. The average income of 12 families who reside in a rural area of the Midwest is $60,213, with a standard deviation of $2009. What are the results if you want to determine at α = 0.05 if there is a difference in the income between families who live in the cities and those who live in the rural areas?

Accept the null hypothesis, the test statistic is less than 1.725.

Reject the null hypothesis, the test statistic is more than 1.725.

Accept the null hypothesis, the test statistic is less than 2.086.

Reject the null hypothesis, the test statistic is more than 2.086.

The American Bar Association reports that the mean length of time for a hearing in juvenile court is 25 minutes. Assume that this is your population mean. As a lawyer who practices in the juvenile court, you think that the average hearing is much shorter than this. You take a random sample of 20 other lawyers who do juvenile work and ask them how long their last case in juvenile court was. The mean hearing length for this sample of...

The Urban Institute in Washington, DC published an article on child-care expenses in American families. According to the report, child-care expenses for a single-parent family are less compared to two-parent families. A random sample of 500 single-parent households had a yearly average child-care expense of $258 with a sample standard deviation of $55. Another random sample of 400 two-parent households showed the average yearly child-care expense to be $297 with a sample standard deviation of $50. Perform a hypothesis test...
