1. Professor wants to explore the relationship between the positive review received per day and the total number of orders received per day on Amazon. Professor randomly selected 7 amazon product links. The data is presented in the table below.

Link #	#of positive reviews received/day	# of orders received/day
1	2	4
2	4	7
3	3	3
4	7	6
5	9	11
6	8	9
7	9	9

= 42,=1764,= 49,=393,= 339

Conduct a hypothesis test using the following steps. Set alpha =.05, two-tailed

Step 1: State the hypotheses in words and symbols

Step 2: Set up the criteria for making the decision, that is find the critical value

Step 3: Summarize the data into the appropriate test-statistic. That is, compute the correlation.

Step4: Evaluate the Null Hypothesis ( Reject or Fail to Reject )

Step5: State your conclusion

What proportion of the variability of the number of orders received can be explained by the variability of the number of positive reviews received?
