I need help solving this problem and see explanation. Thank You
Comparing Global Internet Connections In Exercise 2.138 on page 101, we discuss data on average internet download speeds in nine different countries in order to determine whether internet speed is related to the amount of time users spend online.78 The data are shown in Table 2.36 and are also available in the dataset GlobalInternet2019.
A)What would a positive association mean between these two variables? Explain why a positive relationship might make sense in this context.
B)What would a negative association mean between these two variables? Explain why a negative relationship might make sense in this context.
C)Make a scatterplot of the data, using internet speed as the explanatory variable and time online as the response variable. Is there a positive or negative relationship? Are there any outliers? If so, indicate the country associated with each outlier and describe the characteristics that make it an outlier for the scatterplot.
D)If we eliminate any outliers from the scatterplot, does it appear that the remaining countries have a positive or negative relationship between these two variables?
E)Use technology to compute the correlation. Is the correlation affected by the outliers?
F)Can we conclude that a slower connection speed causes people to spend more time online?
