Question

A video game player insists that the longer he plays a certain computer game, the higher his scores are. The table shows the total number of minutes played and the high score (in thousands of points) achieved after each 5-minute interval. Use α = .01 .

# Min   5   10    15   20    25    30    35    40    45   50   55   60

Score  48.0 53.3 101.9 72.5 121.5 146.0 196.1 118.5 150.5 80.7 36.0 64.8

Find the critical value. (Round to the nearest thousandth. If more than one value is found, enter the largest critical value.)

State the conclusion in words.

1. The sample data support the claim of linear correlation.
2. There is not sufficient sample evidence to support the claim of linear correlation.
