If Ꜫx=12, Ꜫy=42, Ꜫx²=46, Ꜫy²=542, Ꜫxy=157and n =4, find the correlation coefficient,

Explain correlation and its importance.

Summarize the definitions for linear correlation, quadratic correlations and exponential correlations. Provide an example graph of each of the types of correlation along with your summarized definitions.

For each pair of quantities, decide if the correlation coefficient would be close to 1, close to -1, or not be close to 1 or -1. Part: 0/4 Part 1 of 4 (a) The number of hours a student spends studying and the score on that student's exam. The correlation coefficient would be close to 1 Part: 1/4 Part 2 of 4 Part: 2/4 X (b) The number of hours a student spends studying and the number of letters in that student's name. The correlation coefficient would be close to -1 Part 3 of 4 X Ś X Ś (c) The number of hours an overweight person spends exercising and that person's weight. The correlation coefficient would be close to 1 5

Explain how to interpret the absolute value of a correlation coefficient.

If the correlation coefficient r is equal to 0.585, find the coefficient if determination and the coefficient of no determination

Suppose a friend of yours computes a correlation coefficient of +1.10 and comes to you for advice as to how to interpret it. What would you tell your friend?

A correlation value of -0.92 is positive and strong positive and weak positive negative and strong
