QUESTION 18 A researcher notes that there seems to be a difference in the prevalence of high blood pressure among college-educated individuals who consume low amounts of processed foods and the prevalence of individuals who only have a high school education and consume high amounts of processed foods. Use the appropriate hypothesis to test for the independence of the two independent variables presented here at the 5% significance level to ensure confounding has not influenced the study’s results. Then, interpret your response. Diet Low in Processed Foods Normal BP High BP Total College Education 124 55 179 High School Education 69 152 221 Total 193 207 400 Diet High in Processed Foods Normal BP High BP Total College Education 64 85 149 High School Education 98 153 251 Total 162 238 400 The chi square value of 37.724 is higher than the chi square value of 3.84; therefore, we do not reject H0 at the 5% level and reject H1, which states that level…
QUESTION 2 To test the effect of a new medication on pulse rate, the researcher randomly selected the 60 subjects into two groups of 30. New medicine and placebo were given to Group 1 and Group 2, respectively. Below is the Minitab output. Two-Sample T-Test and CI Group 1 N Мean StDev 7.80 SE Mean 30 65.20 1.4 2 30 70.30 8.40 1.5 Difference = mu (1) - mu (2) Estimate for difference: -5.10 95% CI for difference: (-9.29, -0. 91) T-Test of difference = 0 (vs not =): T-Value = -2.44 P-Value=0.018 DF=57 i) State the formula you would use to construct a 95% confidence interval. Include the value of a and degrees of freedom that you will use to find the critical value in the formula

Hence, interpret its meaning.

Discussion Question: In this research study, one group was asked to watch a car accident and were asked to estimate the speed of the car after it "hit" the other car, while a different group also watched an accident but instead were asked to estimate the speed after the cars "collided." Explain why an independent samples t-test was used, and give your own example of a research study in which an independent samples t-test would be the appropriate statistical analysis.
