For many years, TV executives used the guideline that 30% of the audience was watching each of the traditional big three prime-time networks and 10% was watching cable stations on a weekday night. A random sample of 500 viewers in the Tampa-St. Petersburg, Florida, area last Monday night showed that 170 homes were tuned in to the ABC affiliate, 140 to the CBS affiliate, and 140 to the NBC affiliate, with the remainder viewing a cable station. At the 0.02 significance level, can we conclude that the guideline is still reasonable? Ho: The proportions are as stated. H: The proportions are not as stated. State the decision rule using 0.02 significance level. (Round your answer to 3 decimal places.) Reject HO if chi-square > Compute the value of chi-square. (Round your answer to 3 decimal places.) Chi-square value What is your decision regarding Hg? HO. Proportion of viewers as stated. Do not reject Reject Chicken Delight claims that 93% of its orders are delivered within 10 minutes of the time the order is placed. A sample of 80 orders revealed that 72 were delivered within the promised time. At the 0.05 significance level, can we conclude that less than 93% of the orders are delivered in less than 10 minutes? a. What is the decision rule? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.) Reject HO if z < b. Compute the value of the test statistic. (Negative amount should be indicated by a minus sign. Round the intermediate values and final answer to 2 decimal places.) Value of the test statistic c. What is your decision regarding the null hypothesis? H0 : TT2 0.93 Cannot reject Reject
