A characteristic of interest for the elements is called: A. a sample B. a data set C. a variable D. an observation 2. What does the correlation coefficient (r) measure in a correlation analysis? A. The strength and direction of a linear relationship between two variables. B. The causal relationship between two variables. C. The difference between the means of the two groups. D. The variability of a single variable. 3. You work as an analyst for a retail company, and you are interested in understanding how advertising spending (independent variable) affects monthly retail sales (dependent variable). In a simple linear regression equation, what does the regression slope coefficient (B1) represent in this scenario? A. The average monthly retail sales for all companies B. The change in average monthly retail sales is associated with a one-unit increase in advertising spending. C. The…
Consider the following table of data. Complete parts (a) through (c) below. 2 3 4 y 2.00 2.00 2.00 2.50 a. Calculate the correlation coetticient. (Type an integer or decimal rounded to four decimal places as needed.) b. Sketch a graph of the data. Choose the correct answer below. O A. OB. Oc. OD. A c. Based on how closely the data fits a straight line, is the answer to part (a) surprising? Discuss the extent to which the correlation coefficient describes how well the data fit a horizontal line O A. It is surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 0. O B. It is surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 1 or - 1. Oc. It is not surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 1 or -1. O D. It is not surprising. Given how closely the data fits a line, one would expect a correlation coefficient close to 0.
What type of relationship exists between the two variables x and y in the scatter plot? A.Positive correlation B.No correlation C.Negative correlation D.None of the choices
use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what do you conclude about a linear correlation? FORECAST AND ACTUAL TEMPERATURES The table lists actual high temperatures and the high temperatures that were previously forecasted for these same days. The table includes data for ten different days near the author’s home. What does the result suggest about the accuracy of five-day predicted high temperatures?

Statistics Question
Members of the student council are seling bagels during each class period of the school day for a fundrasier. Yu-na made a scatter plot to see if there was a relationship between the class period and the number of bagels sold.Yu-na draws a line of best fit. Which of these lines is the best model for the data?
Answer clearly
Based on the given scatter diagram, choose the correct statement. a. It is a positive correlation. The more time an individual spends running, the higher their body fat tends to be. b. It is a positive correlation. The more time an individual spends running, the lower their body fat tends to be. c. It is a negative correlation. The more time an individual spends running, the higher their body fat tends to be. d. It is a no correlation. The amount of time an individual spends running has no correlation with his/her body fat tends to be. e. It is a negative correlation. The more time an individual spends running, the lower their body fat tends to be.
