Which value of r indicates a stronger correlation: r=0.793 or r= - 0.892? Explain your reasoning. Choose the correct answer below. O A. r= -0.892 represents a stronger correlation because 0.793> - 0.892. O B. r= -0.892 represents a stronger correlation because -0.892 > 0.793. O C. r=0.793 represents a stronger correlation because 0.793 > - 0.892. O D. r=0.793 represents a stronger correlation because -0.892 > |0.793.

Which of the R values below is consistent with a "perfect" correlation?  a. 0.0 b. 0.5 c. -1.0 d. 0.95

The following statement contains an error. Choose the statement that best explains the error. "The correlation between shoe size and height is 0.87 inches" A. Correlation requires that both of the variables be categorical B. When stating the correlation coefficient, one must state whether it is a positive or negative relationship C. This statement does not tell us whether or not shoe size is correlated with height D. When reporting correlation, one does not report units because correlation has no units E. There is no error in this statement

Which r is the strongest correlation? O -0.8 O-0.18 O-0.09 O 0.711 O 0.4

A negative correlation indicates that as the values of one variable increase, the values of a second variable decrease. O True O False

Give an example of two variables that you would expect to have a correlation close to or equal to -1. Give an example of two variables that you would expect to have a correlation close to or equal to 0. Remember that survey question you wrote? Take the class responses to your survey as data related to the one variable of your question. Now, take the list of responses from the survey question that one of your classmates wrote.  Write down both lists of data. (If one sample size happens to be different from the other, cut the larger sample size down to that of the smaller sample size.) Calculate the correlation between the two variables. Describe the linear relationship between these two variables. (data for number 3) How many cars have you had so far in your lifetime? 0,1,1,1,2,2,2,2,3,3,3,3,4,4,5,6,6,7,10.   How many days per week do you exercise? 0,0,0,1,2,3,3,3,3,4,4,4,4,5,5,5,5,6,6,6

answer please

Compute and interpret the coefficient of multiple correlation. Number 4 answer is missing.

Dr. Erie, a researcher at the Moore County Botany Institute, reported the following correlations. The correlation between pH level of soil and tomato weight is r₁ = -0.4. The correlation between hours of sunlight and tomato weight is r2 = 0.1. According to this information, which of the following statements are true? Select all that apply. Larger tomatoes result from more daily hours of sunlight. Larger tomatoes result from higher soil pH level. Tomato size is related more strongly to hours of sunlight than to soil pH level. None of these are true.
