1 . If the p-value of slope is 0.35833333333333 and you are 95% confident the slope is between -10 and 9

a.The p value is less than 0.05 so there is strong evidence of a linear relationship between the variables

b.The p value is not less than 0.05 so there is not strong evidence of a linear relationship between the variables

2. You want to use dataset with two quantitative variables X (advertising) and Y (sales) so you can predict future values of Y (sales) using X (advertising)

You obtain the following sample statistics

The average of X is 4.3 with standard deviation 0.93

The average of Y is 2.8 with standard deviation 0.5

correlation coefficient r = 0.81 so if a future value of x is 1 standard deviation above average so then then the predicted value of y is 0.81 standard deviations above average.

3. If the 95% confidence interval for the slope is between and -9.8 and -7.8

then you are 95% confident that increasing x by 1 will DECREASE y by between 7.8 and 9.8 on average

Be careful with this question select all the correct options

a.The corresponding Pvalue will not be less than 0.05

b.There is not strong evidence of a relationship

c.The corresponding pvalue will be less than 0.05

d.There is evidence of a negative linear relationship

e.There is evidence of a positive linear relationship
