The sponsors of televisions shows targeted at the market of 5 - 8 year olds want to test the hypothesis that children watch television at most 20 hours per week. The population of viewing hours per week is known to be normally distributed with a standard deviation of 6 hours. A market research firm conducted a random sample of 30 children in this age group. The resulting data follows:
| 19.5 | 29.7 | 17.5 | 10.4 | 19.4 | 18.4 |
| 14.6 | 10.1 | 12.5 | 18.2 | 19.1 | 30.9 |
| 22.2 | 19.8 | 11.8 | 19.0 | 27.7 | 25.3 |
| 27.4 | 26.5 | 16.1 | 21.7 | 20.6 | 32.9 |
| 27.0 | 15.6 | 17.1 | 19.2 | 20.1 | 17.7 |
At a .10 level of significance test the sponsors' hypothesis.
Select one:
a.
Do not reject H0, 0.403835 > .10, cannot conclude that children watch TV more than 20hrs/week at .10 level of significance.
b.
Reject H0, 0.403835 > .10, cannot conclude that children watch TV more than 20hrs/week at .10 level of significance.
c.
Reject H0, 0.0875 < .10, cannot conclude that children watch TV more than 20hrs/week at .10 level of significance.
d.
Do not reject H0, 0.403835 > .10, can conclude that children watch TV more than 20hrs/week at .10 level of significance.
e.
Reject H0, 0.0875 < .10, can conclude that children watch TV more than 20hrs/week at .10 level of significance.
