Chatterbug, a social networking site on the Intermet, would like to determine if gender is related to number of minutes per day spent on a Chatterbook account. A random sample of 239 users was taken with the following results: Time spent on Chatterbug Gender 1-25 minutes per day 25 - 50 minutes per day More than 50 minutes per day Males Females 51 32 29 50 27 50 Conduct a hypothesis test based on this sample data, with a = 1%. Based on the sample data can Chatterbug conclude that gender is related to time (minutes per day) spent on a Chatterbug account? (a) State the hypotheses: Ho: The population classifications time spent on Chatterbug and gender are independent H.: The population classifications time spent on Chatterbug and gender are dependent (b) Choose the correct distribution: O Normal Distribution Chi-Square Distribution O T-Distribution
