Joe likes to go to an old arcade and play 8 games of Skeeball every day. On average, he wins a prize on 65% of the games he plays. Today, however, he won only 3 of the 8 games he played. This made Joe think that there must be something wrong with how he is throwing the ball today. However, a friend tells him, "You might be throwir the same way you usually do. People will sometimes have a group of bad games just because of random variation, not because of psychology, or because they are doing anything differently, or any other reason. For someone with your statistics, such random bad days wouldn't even be very rare." Let's see what Joe's friend means. Suppose that Joe's skill level really hasn't changed, so he still has a 65% chance of winning each game he plays, like before. If he plays 8 games a day, on what percentage of days will he win 3 games or fewer? Assume that each game is independent of the others. Fill in the blank: Joe would win 3 games or fewer on % of the days that he plays. (Round to one decimal place as needed)

20 students from economics department were asked about their favourite course. 7 students said statistics, 3 of them said game theory, 9 of them said Microeconomics, 1 student said finance and 0 student said mathematics for economists. Draw a bar chart to represent the above information.(I have briefly shown you a bar chart during lecture. It’s nothing difficult but if you have any confusion, refer to the book or email me)
Helen wants to compare two machines in her factory to see if the wrapping was satisfactory. She wants to know if there is a difference between the two machines. She randomly chooses 56 packs that were wrapped with machine A and finds among them 47 that were satisfactory. She also randomly chooses 25 packs that were wrapped by machine B and notices that 14 of them were satisfactory. Use this information for both parts.
In a traditional class with in-class tests, a question that is often asked after a class exam is, "What was the class average?" If that question is asked and the professor says that the class average was 80, what information do the students gain by knowing that? I want you to focus on both what the individual students knows about their own grade as well as what the students know about the class's grades on that exam.
You are given the chance to play one of two games: One where there is a 20% chance of you winning 8 dollars and an 80% chance of winning 128 dollars. For the second game you have a 20% chance of winning two dollars and an 80% chance of winning 256 dollars. Which lottery is worth more on average, and how much is it worth discrete math
Joe and Maggie take turns mowing the lawn each week. Maggie suggests they try a new system for determining who should mow the lawn. Each week, they will roll two dice and determine the sum of the values. Since the highest possible sum is 12, Maggie will mow the lawn if the sum is 6 or less, and Joe will mow the lawn if the sum is greater than 6. Before agreeing to Maggie's suggestion, Joe wants to check if this plan would be fair. He decides to roll a pair of dice and determine the sum of the values 100 times. The graph shows the results of the 100 trials. Based on his simulation, should Joe agree to Maggie’s plan? (yes/no), because a sum greater than 6 is likely to occur (more than, less then, equal to)(30%, 50%, 75%) of the time

AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…
The past records of a supermarket show that its customers spend an average of $110 per visit at this store. Recently the management of the store initiated a promotional campaign according to which each customer receives points based on the total money spent at the store, and these points can be used to buy products at the store. The management expects that as a result of this campaign, the customers should be encouraged to spend more money at the store. To check whether this is true, the manager of the store took a sample of 14 customers who visited the store. The following data give the money (in dollars) spent by these customers at this supermarket during their visits. 106.13 107.43 124.68 124.88 101.17 72.75 85.45 86.05 100.4 98.84 101.63 95.56 89.40 119.52 Assume that the money spent by all customers at this supermarket has a normal distribution. Using a 2.5% significance level, can you conclude that the mean amount of money spent by all customers at this supermarket after the…
PLEASE HELP SOLVE THE PROBLEM BELOW A candy manufacturer selects mints at random from the production line and weighs them. For one week, the day shift weighed n1 = 194 mints and the night shift weighed n2 = 162 mints. The numbers of these mints that weighed at most 21 grams was y1 = 28 for the day shift and y2 = 11 for the night shift. Let p1 and p2 denote the proportions of mints that weigh at most 21 grams for the day and night shifts, respectively. Give a point estimate of p1 Give the 95% confidence interval for p1 Give a point estimate of p1 − p2 Find the 95% confidence interval for p1 − p2
