Lucy recently asked the servers at her restaurant to only give straws to customers who request them. She thinks that abouthalf of the customers will ask for straws but hopes that the rate will be less than half. She randomly selects 100 customersand finds that 43 of them ask for a straw. To determine if these data provide convincing evidence that the proportion ofcustomers who will ask for a straw is less than 50%, 150 trials of a simulation are conducted. Lucy is testing thehypotheses: Ho: p = 50% and Ha: p < 50%, where p = the true proportion of customers who will ask for a straw. Based onthe results of the simulation, what is the estimate of the P-value of the test?●+●+●●●●●●●●●●●●●●●●●●·●●●●●●●●●●●●●●●●●●●●+●●●●●●●●●●●●●●●+●●●●●●●●●●●●●●●●●●●●●●●·●●●●●●●●●●●●●●●··●●●●●●●●●●●40% 42% 44% 46% 48% 50% 52% 54% 56% 58% 60% 62% 64%Simulated sample percentage of requests for a straw0.03330.050.07330.11

nita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide to eat in the restaurant (as opposed to ordering the food "to go"), so it can make decisions regarding the possible construction of in-store play areas, the attendance of its mascot Sammy at the franchise locations, and so on. Anita's reports that 48% of its customers order their food to go. If this proportion is correct, what is the probability that, in a random sample of 4 customers at Anita's, exactly 3 order their food to go? Round your response to at least three decimal places.
To get from Berkeley to the San Francisco airport (SFO) one can either take a shuttle van or drive. Either way, one must cross the San Francisco Bay Bridge. The shuttle van drops its passengers at the airport departure terminal. If one drives, he or she must park in a lot near the airport, then take a parking shuttle from the parking lot to the airport departure terminal. There is a 40% chance that the Bay Bridge will be congested with traffic. If it is, it takes 1.1 hours to drive to the parking lot. If not, it takes 40 minutes to drive to the parking lot. The parking shuttle runs every 10 minutes and takes 10 minutes to get to the airport departure terminal from the parking lot. Suppose it is equally likely that one must wait 0, 1, or 9 minutes for the parking shuttle once getting to the parking lot, and that the amount of time one must wait is independent of the amount of time it takes to drive to the parking lot from Berkeley. 2, If one takes the shuttle van from Berkeley directly…
Cindy, a financial analyst is studying the relationship between family decisions to borrow money to finance a child’s education and the child’s expected income after graduation. To aid the study, 440 randomly selected families were surveyed with the results provided below. At alpha =0.01, can you conclude that the decision to borrow money is related to a child’s expected income after graduation? Expected income More Likely Less Likely Did not make a difference Did not consider it Less than $20,000 37 10 22 25 $20,000-$45000 28 12 15 16 $45000-$70000 55 9 65 48 Greater than $70000 36 1 29 32 What is the degrees of freedom?

Lucy recently asked the servers at her restaurant to only give straws to customers who request them. She thinks that about half of the customers will ask for straws but hopes that the rate will be less than half. She randomly selects 100 customers and finds that 43 of them ask for a straw. To determine if these data provide convincing evidence that the proportion of customers who will ask for a straw is less than 50%, 150 trials of a simulation are conducted. Lucy is testing the hypotheses: H0: p = 50% and Ha: p < 50%, where p = the true proportion of customers who will ask for a straw. Based on the results of the simulation, the estimated P-value is 0.0733. Using a = 0.10, what conclusion should Lucy reach? Because the P-value of 0.0733 < a, Lucy should reject H0. There is convincing evidence that the proportion of customers who will ask for a straw is less than 50%. Because the P-value of 0.0733 < a, Lucy should reject Ha. There is not convincing evidence that the…
In the Star and Tribune newspaper, there is an article entitled “1 in 8 school buses fail tests." The article says that the overall statewide proportion of school buses that fail safety tests is 9%. However, one bus company has a higher rate of over 12%. Assume that we want a new estimate for the statewide proportion of school buses that fail the safety inspection. We take a sample of 200 buses and find that 20 buses fail the safety inspection. If we construct a 95% confidence interval estimate for the true proportion of all Minnesota school buses that fail the safety tests, what is the upper limit of the interval? (Enter you answer including 3 decimal positions, e.g. .234)
In Class Exercise You are asked to evaluate the effect of a fast acting blood pressure medication. You take a random sample of 200 people from the population and assign half of them at random to take the pill. Of the 100 you told to take the pil| 25 refuse and 75 take it. At the end of a week you check the blood pressure of the group assigned to get the pill and it is 120 on average and the blood pressure of the group assigned to control is 127.5 on average. 1. What is Y;, what is Z;, what is D;? 2. What is the first stage? Estimate and interpret 3. What is the reduced form? Estimate and interpret. 4. What is the effect of the drug on blood pressure?
Sean is the star shortstop for his baseball team. He notices that his team typically scores about half as many runs as he has singles, and that his team is about 10% more likely to win a game for each run scored. How likely is it that the team wins if he has 6 singles? How many singles did Sean hit if the team was 70% likely to win?
Night Owls proportion of MSU students who regularly sleep less than 8 hours each night is less than the value reported by the MSU psychologist. She randomly selects 215 students and asks them, "Do you regularly sleep less than 8 hours each night?" She finds that 77 of the 215 students answered "yes" to the question.

A substance abuse counselor wants to demonstrate the effect of situational stress on alcohol cravings. He recruits two groups of men who are similar in respect to history of alcohol use and demographic variables. He divides them in to two groups. In one group(n=11), the men are exposed to a stressful situation and then asked to complete a measure rating their alcohol cravings on a scale from 0-10, where 0 representsno cravings and 10 represents intense cravings. In the second group (n=10), the men are exposed to a neutral situation and asked to complete the same measure. What test and graph should I create to find out if a stressful situation result in more intense alcohol cravings than a non-stressful situation?
A auto shop wants to examine the proportion of customers that have to return after an appointment. Last year, an examination of 264 customers found that 30.1% had to return after an appointment. You instituted some changes at the auto shop this year, and found from a sample of 326 customers that 22.4% had to return after an appointment. You want to conduct an analysis to determine if there has been an increase in the proportion of customers that need to return after an appointment since the past year, with a = 0. 10. Using this information, what is the critical value of your analysis? Round your final answer to two decimal places. 2.11 1.96 2.33 1.28 1.64
Back in April and May of 1985, the Gallup organization conducted a poll to estimate the percentage of Americans who approved of how President Reagan was handling his job. At the 5% significance level, do the data suggest that the percentage of those who approved of Reagan increased from April to May in 1985? Population 1: April p = 795/1528 = 0.5203Population 2: May p = 840/1528 = 0.5497Show all your steps, setting up your null and alternative hypothesis.
