For the computations regarding correlation coefficient and regression line equation, use an Excel spreadsheet. For hypothesis testing, use a 5% level of significance.
Choices for number 1:
-0.915
-0.871
-0.894
-0.922
Choices for number 2:
moderate negative correlation
strong negative correlation
weak negative correlation
negligible negative correlation
Choices for number 3:
No. Since the absolute value of the computed test statistic is less than the absolute value.
No. Since the absolute value of the computed test statistic is greater than the absolute value.
Yes. Since the absolute value of the computed test statistic is less than the absolute value.
Yes. Since the absolute value of the computed test statistic is greater than the absolute value.
Choices for number 4:
Y = 2.198 - 65.901X
Y = 65.901 + 2.198X
Y = 65.901 - 2.198X
No equation since regression analysis is not recommendable
