In a​ survey, respondents were asked to disclose their political affiliation​ (Democrat, Independent,​ Republican) and also answer the question​ “Would you be willing to pay higher taxes if the tax revenue went directly toward deficit​ reduction?” A contingency table is provided below with the survey results. Determine whether the results suggest there is an association between political affiliation and willingness to pay higher taxes to directly reduce the federal debt. Use the α=0.05 level of significance. What are the null and alternative hypotheses for this​ test?

A nutritionist found a significant relationship between the number of grams of protein consumed per day, x 1 x_1 ​, and a person’s muscle mass index, y y .The relationship can be represented by the regression equation: y ^ = 18 + 0.4 x 1 \hat{y} = 18 + 0.4x_1 Predict the muscle mass index for a person who consumes 70 grams of protein per day.

A medical researcher wishes to try three different techniques to lower the weight of obese patients. The subjects are randomly selected and assigned to one of three groups. Group 1 is given​ medication, Group 2 is given an exercise ​program, and Group 3 is assigned a diet program. At the end of six​ weeks, the reduction in each​ subject’s weight​ (in pounds) is recorded.

Report the decision and conclusion using a significance level of 5%.
