- A car dealer is interested in comparing the average gas mileages of four different car models. The dealer believes that the average gas mileage of a particular car will vary depending on the person who is driving the car due to different driving styles. Because of this, he decides to use a randomized block design. He randomly selects five drivers and asks them to drive each of the cars. He then determines the average gas mileage for each car and each driver. Can the dealer conclude that there is a significant difference in average gas mileages of the four car models? The results of the study are as follows.

(You would have a collection of numbers 1-6.) Now, suppose you wanted to average these numbers. What value would you expect? If the die was rolled 6 times and the results were: 1, 4, 2, 2, 3, 2, then the average of this sample of rolls would be 2.333. This experiment could be peformed again: 6, 5, 2, 1, 1, 4. Now, the average of this sample is 3.167. Obviously, these small samples have a lot of variation in them; however, is there a way to calculate the expected average? If we were to construct a very large sample, rolling this die 1 million times, what would the expected value (mean) be? Luckily, the rules of probability allows us to do this calculation without actually having to roll the die 1 million times! Below, you will find a probability table where all of the possible outcomes from the die are listed. The first column contains the possible outcomes on the die, the second column contains the…23. The Mum Water Company produces and distributes Mum bottled water in Bangladesh. The company wants to determine whether customers have a higher preference for its bottled water than for its main competitor, Fresh bottled water. The Mum Water Company hired a statistician to conduct this study. The statistician selected a random sample of 10 people and asked each of them to taste one sample of each of the two brands of water. The customers did not know the brand of each water sample. Also, the order in which each person tasted the two brands of water was determined randomly. Each person was asked to indicate which of the two samples of water he or she preferred. The following table shows the preferences of these 10 individuals. Page 1 of 2 Person Brand Preferred 1 Mum 2 Mum Mum 4 Mum 5 Mum Fresh 7 Mum Neither 9. Mum 10 Mum Based on these results, can the statistician conclude that people prefer the Mum brand of bottled water over the Fresh? Test at 5% significance level with…
- A container contains 15 diesel engines. The company chooses 8 engines at random, and will not ship the container if any of the engines chosen are defective. Find the probability that a container will be shipped even though it contains 2 defectives if the sample size is 8. The probability the container will be shipped is (Round to the nearest thousandth as needed.)2. In a population it is estimated that 20% have a desired trait of interest for the researcher. The researcher wants to know how many people on average he has to draw from a population to get 2 people with the trait. Use rows 20-24 of the Random Number Table to carry out the simulation. Explain clearly how you set up the problem and report your findings. Answer:students were assigned a quiz that contains 7 independent multiple-choice problems. Each problem was worth 1 point and has 4 choices, where only one of them is correct. A pirate, who does not understand probability and statistics, disguises himself as a clever student and tried to pass one of the quizzes. Unlike our students, he is not able to solve the problems and, thus, decides to randomly choose an answer for each problem. Let X be a random variable representing the score of the pirate on the FIRST problem of the quiz. What distribution does X follow?

- The school district sets up two locations to help students with technical difficulties over the summer. They believe the technicians they have assigned to location 2 are being lazy and not helping students as much as they should be so they take a random sample of 15 students from each of the two locations and ask if their technical issue had been resolved (over 200 students had asked for assistance at each location). Twelve of the 15 students from location 1 reported their technical issue had been resolved and 8 of the 15 students from location 2 reported their technical issue had been resolved. Is this convincing evidence that the technicians from location 2 are being lazy and not helping students as much as those from location 1?A car dealer is interested in comparing the average gas mileages of four different car models.
