Relationship between two variables:

Scatterplots A:

In this scatter plot, it is clear that both variables are in same direction. That is, both quantitative variables are increasing or decreasing together and it is approximately linear. Therefore, the relationship is positive linear.

Scatterplot B:

In this scatter plot, there is no any particular pattern and the data are scattered randomly. Here, the direction of two variables cannot be identified. Therefore, the relationship is no relationship.

1) In what way is the point unusual? Does it have high leverage, a large residual, or both?

2) Do you think that point is an influential point?

3) If that point were removed, would the correlation be- come stronger or weaker? Explain.

4) If that point were removed, would the slope of the re- gression line increase or decrease? Explain

a. Find the mean of the sample.

b. Find the standard deviation of the sample.

c. Construct a 95% Confidence Interval estimate for the mean age at which a baby first crawls. (Assume the data comes from a normal distribution.)

Given info:

The mean SAT math score is 528 with a standard deviation of 105. The mean SAT verbal score is 475 with standard deviation is 98. A student in the graduating class scored 740 on SAT math and 715 on SAT verbal.

b. To identify the test did the student do better.
