If the coefficient of correlation is equal to -0.95 the relationship between the two variables will be O a. Very high O b. Moderate C. Rare d. Very low

Dr. Wright, a researcher at the Young County Botany Institute, reported the following correlations. The correlation between pH level of soil and tomato weight is r₁ = 0.8. The correlation between hours of sunlight and tomato weight is r2 = 0.7. 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 lower soil pH level. ✔Tomato size is related more strongly to hours of sunlight than to soil pH level. None of these are true.

If you have a correlation (r=.90), the coefficient of determination would be:

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

If you have 10 variables when computing correlation coefficients how many unique coefficients will you have overall?

Which of the following correlation coefficients indicate the strongest relationship between two variables?    A   .20 B    .87 C    .80 D    -.95

For each of the following, indicate whether a correlation is most likely POSITIVE, NEGATIVE or NC (no correlation possible). The number of calories consumed and a person's weight loss The age of a child and the kind of pets owned Number of hours spent partying and GPA The age of a car and its mileage Weekly ice cream sales and weekly average temperature

For each pair of quantities, decide if the correlation coefficient would be close to 1, close to -1, or not be dose to 1 or-1, Part: 0/4 Part 1 of 4 (a) The number of years of education completed and age of the car that person drives. The correlation coefficient would (Choose one) be dose to 1 be dose to -1 not be close to 1 or -1

Which of the following values represents the weakest correlation between two variables? о г= -0.17 г= 0.07 K r=0.45 r=-0.62 r = 0.81 00000

e. Compute the covariance and correlation coefficient r between the right tire pressure. f. How do you know the relationship between pressure in the left and right tires is positive. g. What value would a correlation coefficient (r) be close to if there was no (linear) relationship between the 2 tire pressures?
