Question
A recent broadcast of a television show had a 10 ?share, meaning that among 5000 monitored households with TV sets in? use, 10?% of them were tuned to this program. Use a 0.01 significance level to test the claim of an advertiser that among the households with TV sets in? use, less than 15?% were tuned into the program. Identify the null? hypothesis, alternative? hypothesis, test? statistic, P-value, conclusion about the null? hypothesis, and final conclusion that addresses the original claim. Use the? P-value method. Use the normal distribution as an approximation of the binomial distribution. Identify the null and alternative hypotheses. Choose the correct answer below. A. H0?: pequals0.85 H1?: pnot equals0.85 B. H0?: pequals0.85 H1?: pgreater than0.85 C. H0?: pequals0.15 H1?: pnot equals0.15 D. H0?: pequals0.15 H1?: pgreater than0.15 E. H0?: pequals0.85 H1?: pless than0.85 F. H0?: pequals0.15 H1?: pless than0.15
Explanation / Answer
Given 10 ?share, meaning that among 5000 monitored households with TV sets in? use
Using a 0.01 significance level
Ho: p? 0.15
H1: p<0.15
z = (0.10-0.15)/sqrt(0.15x0.85/5000) = -9.90
