Show work in order to receive credit. 11. What does the scatterplot show regarding the variables? 12. Specify the line of best fit from the regression output. 13. Specify the slope of the regression line and interpret it in context of the data. 14. Specify the intercept of the regression line and interpret it in context of the data. 15. Predict the celluluar percentage for a country with a GDP value of 12 16. Does the output seem to support the idea that the higher the GDP for a country, the higher the percent of the population in a country that uses cell phones? Justify your response. ge the model?

Explanation / Answer

Result:

11). There is positive linear relation between GDP and cellular %.

12).

Cellular % = -5.1904+2.2402 * GDP

13).

Slope=2.2402

When GDP increases by 1, cellular % increases by 2.2402.

14).

Intercept= -5.1904

When GDP =0, the cellular % is -5.1904.

15).

When GDP=12,

Predicted Cellular % = -5.1904+2.2402 * 12

=21.692

16).

Yes, since the regression coefficient is positive, correlation also positive.

Therefore higher GDP associated with higher cellular %.

17).

Since 29.3 is an outlier, removal of this point will change the model.
