The authors of a paper on perceptions of video games carried out an experiment to determine if restrictive labels on video games actually increased the attractiveness of the game for young gameplayers. Participants read a description of a new video game and were asked how much they wanted to play the game. The description also included an age rating. Some participants read thedescription with an age-restrictive label of 7+, indicating that the game was not appropriate for children under the age of 7. Others read the same description, but with an age-restrictive label of12+, 16+, or 18+. The following data for 12- to 13-year-old boys are consistent with summary statistics given in the paper. (The sample sizes in the actual experiment were larger.) For purposes ofthis exercise, you can assume that the boys were assigned at random to one of the four age label treatments (7+, 12+, 16+, and 18+). Data shown are the boys' ratings of how much they wantedto play the game on a scale of 1 to 10.7 6 57+ label48412+ label871079479 8 6 7 4 8 9 6 716+ label796 8 76 8910 818+ label10Do the data provide convincing evidence that the means of the ratings associated with the game descriptions by 12- to 13-year-old boys is not the same for all four restrictive rating labels?

2. The table consists of five actual low temperatures and the corresponding low temperatures that were predicted five days earlier. The forecast temperatures appear to be very different from the actual temperatures, but is there sufficient evidence to conclude that the mean difference is not zero? Use a 0,05 significance level to test the claim that there is a difference between the actual low temperatures and the low temperatures that were forecast five days earlier. 1 Actual Low Forecast Difference 16 -5 16 Oll 6 -5 20 DELL & 23 22 8 9 15

5. The Instagram handle @getfollowers claims that they can increase the number of followers someone has on Instagram. In March 2015 the mean number of followers for a US teen was 150, so a random sample of 12 US teens with 150 followers was taken. The following is the number of followers, which is normally distributed, these US teens had after they paid @getfollowers for their help. Using a 0.01 level of significance, determine whether @getfollowers is effective at increasing the number of Instagram followers. 160 200 152 150 145 151 162 158 156 149 154 170 Null and Alternative Hypothesis
