Entertainment Software Association would like to test if the average age of "gamers" (those that routinely play video games) is more than 30 years old. A random sample of 33 gamers was selected and their ages were recorded. Assume that the standard deviation for the population of the age of gamers is 4.7 years and the true population mean for the age of gamers is 31.2 years. Using α = 0.02, beta equals ________.A) 0.0434B) 0.1247C) 0.2918D) 0.7224

A survey was sent out to re-evalute the proportion of people who play games on pc computers, as the last study on the topic had been gathered four years prior. This survey was done specifically to test the possibility that fewer people are playing games on pc computers. The previous study found that 81% of people were playing games on pc computers. The current study, with 861 participants, found that 53% of people who responded play on a pc computer....

pt 1 Information A survey of people who own smartphones found that 35% of people check their phones at least once an hour. These people are called "constant checkers. Suppose you were to draw a random sample of 10 smartphone owners Question 1 (1 point) The number of constant checkers in the sample has a binomial distribution. What are n and p?

A student at a junior college conducted a survey of 20 randomly selected full-time students to determine the relation between the number of hours of video game playing each week, x, and grade-point average, y. She found that a linear relation exists between the two variables. The least squares regression line that describes this relation is ģ= -0.0564x + 2 9482 (a) Predict the grade-point average of a student who plays video games 8 hours per week. The predicted grade...

A sample survey found that 1063 of a sample of 2054 adults reported that they played video games. Suppose we want to use this sample to test the claim that the proportion of all adults who play video games is lower than 50%. Assuming all necessary assumptions are met, is this hypothesis test a left-tailed, right-tailed, or two-tailed test?
