Question

You wish to determine if there is a linear correlation between the two variables at a significance level of α=0.01. You have the following bivariate data set.

x y
39.3 36.4
52.7 73
50.3 79.8
51.3 71
42 50.8
44.7 74.9
59.2 39.5
54.1 31.6
43.5 90.5



What is the critival value for this hypothesis test?
rc.v. = 

What is the correlation coefficient for this data set?
r = 

Your final conclusion is that...

  • There is insufficient sample evidence to support the claim the there is a correlation between the two variables.
  • There is sufficient sample evidence to support the claim that there is a statistically significant correlation between the two variables.

Note: Round to three decimal places when necessary.
