A random sample of twenty-five adult citizens of the U. S. were asked to estimate the average income of all U. S. households. The mean estimate as $45,000 and the standard deviation among the estimates was $15,000. Based on this data, find the 95% confidence interval for the mean estimate of the average income.

Use the converse of the side-splitter theorem to determine if tu || rs. which statement is true? line segment tu is parallel to line segment rs because 32/36 = 40/50 line segment tu is not parallel to line segment rs because 32/36 not equal 40/50. line segment tu is parallel to line segment rs because 32/36 = 40/50. line segment tu is not parallel to line segment rs because 32/36 not equal 40/50 .
