Researchers want to know if playing violent video games increases aggression levels. They know that the typical teenager scores an average of μ = 4 on a test of aggression. To evaluate their hypothesis, they take a random sample of n = 5 teenagers and have them play violent video games for two hours. After playing the games the teenagers then are measured with the aggression test, resulting in the following scores: X 4 7 5 6 6 (a) Identify...

Please answer with clear steps thanks. A video game company is studying teenagers’ time spent playing video games weekly, in Hong Kong and Taiwan. Assume that the time spent playing video games by teenagers in Hong Kong and Taiwan has a normal distribution for both populations of teenagers and that the standard deviations for the two populations are equal. A sample of 13 teenagers from Hong Kong showed that the mean time they spend playing video games is 24 hours...

A researcher is interested in studying the effect of playing video-games on reaction time. Specifically, he thinks that playing a videogame will change reaction times, but he doesn’t know if it will make subjects faster or slower. He collects the following reaction times (in milliseconds) from a sample of 10 subjects before and after playing a video game for one hour. Before Playing a Video Game (T1) After Playing a Video Game (T2) Difference Score (D) = T1-T2 360 374...

Directions: First, write a simple hypothesis. State your hypothesis in such a way that it could be tested. Here are some examples: • Musical ability is an inherited trait. • People who play video games for more than 2 hours every day are introverted. • People who are early risers are more successful. • People who set long term goals are no more successful as people who do not set long term goals. • Adults who have positive relationships with...

Most video games have several difficulty settings, from "Easy" to "Hard" (many of these have very colorful names). A video game designer wants to determine how to structure the difficulty levels for a new game so that the average time it takes the typical player to play through "Hard" mode is longer than the time to play through "Easy" mode. A sample (Group 1) of 19 typical players took an average of 6.6 hours to complete the game on "Hard",...
