Hi Expert, I need help. Thanks Judge and Cable (2010) report the results of a study demonstrating a negative relationship between weight and income for a group of men. Following are data similar to those obtained in the study. To simplify the weight variable, the men are classified into five categories that measure actual weight relative to height, from 1 = thinnest to 5 = heaviest. Income figures are annual income (in thousands), rounded to the nearest $1,000. Weight Income 4 151 5 88 3 52 2 73 1 49 3 92 1 56 5 143   These data show a positive relationship between weight and income for a sample of men. However, weight was coded in five categories, which could be viewed as an ordinal scale rather than an interval or ratio scale. If so, a Spearman correlation is more appropriate than a Pearson correlation. Convert the weights and the incomes into ranks and complete the table that follows. Ranks X Y XY   8     7     6…

A random sample of boarding school students was asked how many 8-ounce servings of soda they had consumed on a certain Sunday and how many hours of sleep they got that night. Their responses are displayed in the scatter plot below (a) Which variable is the explanatory and which is response? Identify if each variable is categorical or quantitative? Explanatory:______________________ Categorical or quantitative (circle one) Response:________________________ Categorical or quantitative (circle one) (b) What is the y-intercept of the least-squares regression line for this data? (b) Interpret the y-intercept by filling in the blanks: In general, a boarding school student who drinks ________ servings of soda tends to get Approximately ________ hours of sleep. (c) Interpret the meaning of r2 = 0.613 in this setting by filling in the blanks. The ___________________ for the LSR line, the number of _________________ that a boarding school student consumes can predict how much…

I WILL UPVOTE IF IT IS ORIGINAL, COMPLETE, CORRECT, OR TYPEWRITTEN. THANK YOU VERY MUCH. Burning fuels in power plants and motor vehicles emit carbon dioxide (CO2), contributing to global warming. The table at the right displays CO2 emissions per person from countries with at least 20 million populations. (a) What is the variable of interest? How do you classify it? (b) Make a histogram of the data using classes of width 2, starting at 0. Show the frequency distribution table and create the Histogram of the data. Be mindful of submitting a correct graph. (c) Describe the shape, center, and spread of the distribution. Which countries are outliers? For a description of the shape, center, and spread, put your response in paragraph form. Select the most appropriate measure of center and measure of spread to describe the distribution. Also, do not forget to interpret the values based on the given context. Lastly, do not forget to include the unit of measurements. For outliers, show your…
