Quikly support which is cheaper: eating out or dining in? The mean cost of a flank steak, broccoli and rice bought at the grocery store is $ 13.04 (Money, msn website, November 7, 2012).A sample of 100 neighborhood restaurants showed a mean price of $12.75 and a standard deviation of $2 for a comparable restaurant meal. Develop appropriate hypotheses for a test to determine whether the sample data support the conclusion that the mean cost of a restaurant meal is less than the fixing a comparable meal at home. Using the sample from the 100 restaurants, what is the p-value? At α=.05, what is your conclusion? Repeat the preceding hypothesis test using the critical value approach? P287 Q37 The U.S Bureau of labor statistics report that 11.3% of U.S workers belong unions (BLS website January 2014) .suppose a sample of 400 U.S workers is collected in 2014 to determine whether union efforts to organize have increased union membership. Formulate the hypotheses that can be used to determine ehether union membership increased in 2014. If the sample results show that 52 of the workers belonged to unions what is the p-value for your hypothesis test? At α=.05 what is your conclusion?
