Critics of television often refer to thedetrimental effects that all the violence shown ontelevision has on children. However, there maybe another problem. It may be that watching television also reduces the amount of physical exercise, causing weight gains.

The following regression estimates show the relationship between the number of kilograms (in kgs) a child is overweight by, and the number of hours of television viewing per week

overweight=0.55+0.13 hours(0.27)(0.04)

Standard errors are shown in the brackets. The sample size is N=1800.

Using a significance level of 5%, we want to test the hypothesis that the population slope parameter equals to 0. The t-statistic and the conclusion of the test are:

Group of answer choices

t=0.13. Do not reject the null.

t=3.25; Reject the null.

t=3.25; Do not reject the null.

t=2.04; Reject the null.
