In the third week of July, a random sample of 40 farming regions gave a sample mean of x = $6.88 per 100 pounds of watermelons. It is known that o = $1.92 per 100 pounds of watermelons. What can we assert with 98% confidence about the maximum error? (Reference: Agricultural Statistics, U.S. Department of Agriculture) %3D 2.

The red circles represent the sample means of the two groups. Both graphs have 50 observations in the 0-group and 50 observations in the 1-group and the axes on both graphs are identical. The difference between group averages is also the same (group-1 average is 37 higher than group-0). Below are the results of t-tests for the difference in means for each outcome. The results are in no particular order.

Not enough information to determineChi-Square Test of Homogeneity Practice An urban economist wants to determine whether the region of the US a resident lives in is associated with their general level of satisfaction with life. He randomly selects 150 residents 18 years of age or older from 4 geographic regions of the US: East, South, Midwest, and West. He asks: "are you satisfied or dissatisfied with the way things are going in the United States at this time?" Is there evidence that satisfaction ratings are not the same for all four regions?
