3. A State Highway Patrol periodically samples vehicles at various locations on a particular highway to test the hypothesis that the average speed exceeds the set limit of 70 mph. These locations are the best locations for radar patrol cars to catch speeders. At a particular location, a random sample of 30 vehicles shows a mean driving speed of 73.2 mph with a standard deviation of 8.1 mph. Is this location a candidate for radar patrol? Test using a 5% significance level. A. Sketch and label the distribution of the test statistic. Shade the distribution to show the p- value AND calculate the p-value. B. What is the decision at the 5% level? Are the results significant? C. State your conclusion using a well written sentence.

MC Qu. 10-64 Sales at a fast-food restaurant average... Sales at a fast-food restaurant average $6,000 per day. The restaurant decided to introduce an advertising campaign to Increase daily sales. In order to determine the effectiveness of the advertising campaign, a sample of 49 day's sales were taken. The sample showed average daily sales of $6,300. From past history, the restaurant knew that its population standard deviation is about $1,000. If the level of significance is 0.01, have sales increased as a result of the advertising campaign? Multiple Choice Fail to reject the null hypothesis. Reject the null hypothesis and conclude the mean is higher than $6,000 per day. Reject the null hypothesis and conclude the mean is lower than $6,000 per day. Reject the null hypothesis and conclude that mean equal to $6,000 per day.

A food distribution company claims that a restaurant chain receives, on average, 26 pounds of fresh vegetables on a daily basis. The standard deviation of these shipments is known to be 4.4 pounds. The district manager of the restaurant chain decides to randomly sample 35 shipments from the company and finds a mean weight of 24.7 pounds. Test at a 3% level of significance to determine whether or not the food distribution company sends less than 26 pounds of fresh vegetables. a. Check the TWO requirements that are satisfied. The Central Limit Theorem applies. The a distribution is normal since n > 30. The a distribution is normal since the x distribution is normal. The p distribution is normal since np > 5 and nq > 5.
