This Question: 1 pt 4 of 10 (0 complete) This Test: 10 pts possible The data below shows the annual salaries (in millions) and the number of viewers (in millions) of eight television actors and actresses. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using -0.05. Is there sufficient evidence to conclude that there is a linear correlation between the two variables? 97 13 10 32 ewers (y) 10.1 9.9 13.1 What are the null and alternative hypotheses?

The statistical software output for this problem is:
Simple linear regression results:
Dependent Variable: y
Independent Variable: x
y = 7.245482 - 0.0064301431 x
Sample size: 8
R (correlation coefficient) = -0.052186049
R-sq = 0.0027233837
Estimate of error standard deviation: 4.1648487

Analysis of variance table for regression model:
Hence,
Null and Alternative hypotheses: Option C is correct.
Graph D is correct.
r = -0.052
t = -0.128
P - value = 0.902
Greater; is not
Option B is correct.
