The sample data below are the index of exposure to radioactive waste for nine different geographic regions and cancer mortality rates (deaths per 100,000).
Using a 1% level of significance,do the data below support the claim that a higher index of exposure is associated with a higher cancer mortality rate?

Question

The sample data below are the index of exposure to radioactive waste for nine different geographic regions and cancer mortality rates (deaths per 100,000).  
Using a 1% level of significance,do the data below support the claim that a higher index of exposure is associated with a higher cancer mortality rate?

The Answer is

:No linear relationship between the index of exposure and cancer mortality rate,

= 0.

:There is a positive linear relationship between the index of exposure and cancer mortality rate, :No linear relationship between the index of exposure and cancer mortality rate, = 0. :There is a positive linear relationship between the index of exposure and cancer mortality rate, > 0. t = 6.51 P-value = 0.00017 Reject .With the low P-value,the data provides strong evidence of a positive linear relationship between index of exposure and cancer mortality rate.

> 0.
t = 6.51
P-value = 0.00017
Reject :No linear relationship between the index of exposure and cancer mortality rate, = 0. :There is a positive linear relationship between the index of exposure and cancer mortality rate, > 0. t = 6.51 P-value = 0.00017 Reject .With the low P-value,the data provides strong evidence of a positive linear relationship between index of exposure and cancer mortality rate.

.With the low P-value,the data provides strong evidence of a positive linear relationship between index of exposure and cancer mortality rate.
