Some studies havesuggested that a nightly glass of wine may not only take theedge off a day but also improve health. Is wine good for yourhealth? A study of nearly 1.3 million middle-aged Britishwomen examined wine consumption and the risk of breastcancer. The researchers were interested in how risk changedas wine consumption increased. Risk is based on breast cancerrates in drinkers relative to breast cancer rates in nondrinkersin the study, with higher values indicating greater risk. In par-ticular, a value greater than 1 indicates a greater breast cancerrate than that of nondrinkers. Wine intake is the mean wineintake, in grams per day, of all women in the study who drank

A regression analysis was performed to predict weight (y, in kg) using height (x, in cm) among 150 children. The coefficient of determination was . Which of the following is a valid interpretation? a. For each 1-cm increase in height, weight tends to increase by about 0.32 kg b. There is no association between weight and height c. Height accounts for about 32% of the total variability in weight d. The correlation between weight and height is about 0.32
Refer to the correlation table for this question, The data come from Wave 5 of the Arab Barometer survey in Kuwait and were collected in 2019. In this analysis, we see the correlation between age and years of education (Pearson's R= -0.2729) with the p-value (0.0000) below. Explain what a correlation coefficient is and interpret the one you see here. edu_ye~s age edu_years 1.0000 age -0.2729 1.0000 0.0000
A study reported a correlation between height and weight r = .5, p < 0.05. What is the proportion of variability in people's weight that can be explained by differences in height? O 0.71 0.5 0.05 0.25
Which scatter plot shown has a correlation coefficient, r, closest to 0?
Select the most appropriate response. If the correlation between a person’s age and annual income is 0.60, then the coefficient of determination tells us that: 36% of the variation in a person’s annual income can be explained by the predictor variable age. 36% of a person’s annual income can be explained by their age 60% of the variation in a person’s annual income can be explained by the predictor variable age 60% of a person’s annual income can be explained by their age
