15% of those surveyed described their health as poor, 26% as good, 40% as very
good, and 19% as excellent. A health professional in Chicago wanted to determine
if people in Chicago had similar feelings toward their health. In a sample of 600
people in Chicago, 70 described their health as poor, 180 as good, 210 as very
good, and 140 as excellent.
Given an a= .05, what is the result of the chi-squared test?
A. There is not evidence to reject the claim that the proportions are equal
because the test value is less than the critical ?
2 value.
B. There is evidence to reject the claim that the proportions are equal because
the test value is greater than the critical ?
2 value.
C. There is not evidence to reject the claim that the proportions are equal
because the test value is greater than the critical ?
2 value.
D. There is evidence to reject the claim that the proportions are equal because
the test value is less than the critical ?

please help with both, thank you very much!
Assume that the weights of adult women are normally distributed, and that the population standard deviation of weights of all women is o = 29 lb. A researcher claims that the weights of supermodels vary less than the weights of women in general. To test the claim, a random sample of nine supermodels is selected, with data (in pounds) shown as below: 125 119 128 128 119 127 105 123 115 Using...

A company surveyed adult Americans about their consumer debt. They reported that 46% of Millennials (those born between 1980 and 1996) and 60% of Gen Xers (these born between 1965 and 1971) did not pay off their credit cards each month and therefore carried a balance from month to month. Suppose that these percentages were based on representative samples of 450 Millennials and 300 Gen Xers. Is there convincing evidence that the proportion of Gen Xers who do not pay...
