Question

1. The Nielsen Company measured connection speeds on home computers in seven different countries. The table shows the percent of internet users with a ""fast"" connection and the average amount of time spent online in hours per week. Country % Fast Connection (x) Hours Online (y) United States 70 26 Germany 72 28 Australia 64 23 United Kingdom 75 28 France 70 27 Spain 69 27 Italy 64 24 a. [3 pts] Make a scatterplot and describe the association between % Fast Connection and Hours Online. Include all 4 characteristics and the correlation coefficient

Answer 1

To create a scatterplot, we can plot the percent of internet users with a "fast" connection on the x-axis and the average amount of time spent online in hours per week on the y-axis.

scatterplot

The scatterplot shows a positive association between % Fast Connection and Hours Online. As % Fast Connection increases, there is generally an increase in Hours Online.

The association appears to be fairly strong, as the points cluster relatively tightly around the line of best fit.

There is no apparent non-linear pattern in the data, as the points do not seem to follow a curve or any other non-linear shape.

The correlation coefficient between % Fast Connection and Hours Online is r = 0.864, indicating a strong positive correlation between the two variables.
