The McClatchy News Service (San Luis Obispo Telegram-Tribune, June 13, 1991) reported on a study of violence on television during primetime hours. The following table summarizes the information reported for four networks: Mean Number of Network Violent Acts per Hour ABC 15.6 CBS 11.9 FOX 11.7 NBC 11.0 Suppose that each of these sample means was computed on the basis of viewing n 50 randomly selected primetime hours and that the population standard deviation for each of the four networks is known to be s 5. a. Compute a 95% confidence interval for the true mean number of violent acts per prime-time hour for ABC. b. Compute 95% confidence intervals for the mean number of violent acts per prime-time hour for each of the other three networks. c. The National Coalition on Television Violence claims that shows on ABC are more violent than those on the other networks. Based on the confidence intervals from Parts (a) and (b), do you agree with this conclusion?Explain.
STP 231 lectures covering 2.12.4 I.) 2.1 section about variables. Variables are things that are a part of your study that can be defined. Upper case letters represent the definition of the variable, which could be height, gender, number of home runs, etc. Lower case letters represent values of the variable, which could be six foot tall, number of males, 200 home runs, etc. A. Numeric variable: the variables take on numbers, its quantitative. i. Discrete: a numerical variable with a limit. Like the number of seats in a stadium. ii. Continuous variable: a numerical variable without a limit. Like a measurement be
