QUESTION 3. There have been 5 quizzes so far in Michael's Molecular Biochemistry course, and Michaelhas scored 50, 48, 63, 76 and 41. He's not a great student. But there will be 3 more quizzes, and ifMichael averages 67 for all the quizzes, the professor will give him a C and he will be able to enroll inAdvanced Molecular Biochemistry next semester.What does Michael need to average on the last 3 quizzes to get the C ?

We know that the average of the given set of numbers is equal to the ratio of the sum of the numbers…

Luke's teacher has assigned each student in his class an online quiz, which is made up of 10 multiple-choice questions with 4 options each. Luke hasn't been paying attention in class and has to guess on each question. However, his teacher allows each student to take the quiz three times and will record the highest of the three scores. A passing score is 6 or more correct out of 10. We want to perform a simulation to estimate the score that Luke will earn on the quiz if he guesses at random on all the questions. The dotplot shows Luke's simulated quiz score in 50 trials of the simulation. Doug is in the same class and claims to understand some of the material. 1 N 10000 2 …………………………………at 3 …………………… 4 3 ……………………●●●●●▬ 5 Simulated quiz score -●●●●● 10 6 7 If Doug scored 8 points on the quiz, is there convincing evidence that he understands some of the material? Why or why not? Yes, it is unlikely that Doug would score higher than 6 out of 10 based upon randomly guessing the answers. Since…
My neighborhood has a lot of dogs. In fact, when I walk my dog, Wrigley, only 2% of the time do we not see any other dogs. Gary has three dogs (Salsa, Nacho, and Dublin), and we see only Gary and his dogs about 30% of the time when we are on a walk. Lesley has two dogs (Buster and Oreo), and we see only Lesley and her dogs 20% of the time when we are on a walk. Gary and Lesley’s dogs don’t get along; we never see them at the same time. Margo has one dog (Bond), and we see only Margo and Bond 25% of the time when we are on a walk. 10% of the time we see Margo and Lesley. What is the probability that Wrigley and I see both Gary (Salsa, Nacho and Dublin) and Margo (Bond) on a walk? What is the probability we see at least one dog owner on our walk? What is the probability we see only Margo or only Gary? Are the events seeing Gary and seeing Margo independent? EXPLAIN briefly. Are the events of seeing Lesley and seeing Gary mutually exclusive? EXPLAIN briefly.

I am going to celebrate my birthday at Altitude this weekend. I told 10 of my friends that I want them to join me, but that they have to tell me if they want to go fast, because I can only take 4 people with me. How many different groups of 4 friends could come with me to Altitude?
Watching all these drones buzz back and forth is giving you eyestrain. But you can’t just count every single drone - how could you ever know that you had caught them all? You instead take the following approach: you build a taser-net that you can use to stun and catch drones (much more fun than just watching), before tagging them and re-releasing them into the wild. Working for a week, you manage to tag 400 drones, releasing them back into the wild. After waiting a week, you start catching drones again. Catching another 400 drones, you find that 270 of the drones you’ve caught are tagged, meaning you’d caught them before. 130 of your new catch are untagged, meaning this is the first time that you’ve caught them. Assume drones were equally likely to be caught at all times. Before catching the second batch of drones, there were 400 tagged drones in the wild, the rest were untagged. 1) After catching the second batch of drones, what is the smallest number of drones N that might be in the…
MAKE SURE YOU SELECT 2 ANSWERS FOR THIS QUESTION - Type of test and hypothesis. Professor Ratzo wonders if rats will run a maze faster for some kinds of foods than for others. He randomly assigns 30 rats to one of three conditions, 10 rats to each condition. Group 1 gets buttered bread at the end of the maze, Group 2 gets cheddar cheese, and Group 3 gets honey- glazed ham. The number of seconds each rat took to run the maze is recorded. The hypothesis is that type of food makes a difference in rat running time. Choose the type of test you should use to test this hypothesis? Then choose the correct hypotheses in symbol notation (or words if symbol is not appropriate).

After running a mile a day over a period of two weeks, the average amount of weight loss is 2.5 pounds. A dietitian, who publishes health articles in a newspaper, states their new diet program helps with additional weight loss when combining their special diet with running a mile a day over a period of two weeks. Interested in studying the dietitian's article further, you ask friends who have tried the dietitian's new program and you determine their weight loss to be 3.0 pounds in a two-week period, on average. As you set up a hypothesis test to determine if the dietitian's article is correct, what is the dietitian's claim?
Imagine you have some workers and some handheld computers that you can use to take inventory at a warehouse. There are diminishing returns to taking inventory. If one worker uses one computer, he can inventory 125 items per hour. Two workers sharing a computer can together inventory 175 items per hour. Three workers sharing a computer can together inventory 225 items per hour. And four or more workers sharing a computer can together inventory fewer than 235 items per hour. Computers cost $100 each and you must pay each worker $25 per hour Instructions: In parts a and b. round your answers to two decimal places in part c, enter your answer as a whole number. a. If you assign one worker per computer, what is the cost of inventorying a single item? b. What is the cost if you assign two workers per computer? What if you assign three? c. How many workers per computer should you assign if you wish to minimize the cost of inventorying a single item? workers

A 7th grade science teacher would like to know if spending more time doing class experiments will help his students preform better on tests. In a day, he teaches 4 periods of science, so for his 1st and 3rd period classes, he taught as he normally does with mostly lectures and occassional class experiments. For his 2nd and 4th period classes, he did a class experiment everyday with minimal lectures. There were n=25 different students in each of his classes. He then wanted to compare the exam averages between his classes to see if student preformance was significantly different. Which statistical tests should he use?
