A researcher hypothesizes that the attraction one feels for a potential partner increases the anxiety one feels during the first date. Higher numbers indicate higher attraction and anxiety (on a scale of 1-7 for both). She obtains a sample of 85 participants and from that computes the covariance, and standard deviations for anxiety and attraction, reported below. For this question, what is the correlation between attraction and anxiety?

Covariance = 0.90

sd(attraction) = 2.30

sd(anxiety) = 2.70

Make sure to enter only the correlation in your answer and carry it out two decimal places (e.g., .45). Use the formula above.

Interpret the correlation you obtained in the previous question.

Go to the web page below and compute the CI for the correlation. Use the correlation you computed and the sample size given you in Question 1. Use the .95 interval that the website reports (it's the first row). Do you reject the null hypothesis? Why or why not?
