An individual named Claudius is located at the point 0 in the accompanying diagram.A2B2A3B10,B3A1B4A4Using an appropriate randomization device (such as a tetrahedral die, one having four sides), Claudius first moves to one of the fourlocations B,, B2, B3, B4. Once at one of these locations, another randomization device is used to decide whether Claudius nextreturns to 0 or next visits one of the other two adjacent points. This process then continues; after each move, another move to oneof the (new) adjacent points is determined by tossing an appropriate die or coin.(a) Let X = the number of moves that Claudius makes before first returning to 0. What are possible values of X?О 2, 3, 4, ...2, 4, 6, ...(1, 00)[2, 00)Is X discrete or continuous?discretecontinuous(b) If moves are allowed also along the diagonal paths connecting 0 to A,, A,, Az, and A, respectively, what are possible values ofX?О 2, 3, 4, ...2, 4, 6,...(1, c0)[2, co)Is X discrete or continuous?discretecontinuous

rch A computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. Assembly times can vary considerably from worker to worker, and the company decides to eliminate this effect by selecting 12 workers at random and timing each worker on each assembly process. Half of the workers are chosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is recorded, as shown in the table below.

A computer manufacturer is interested in comparing assembly times for two keyboard assembly processes. Assembly times can vary considerably from worker to worker, and the company decides to eliminate this effect by selecting 8 workers at random and timing each worker on each assembly process. Half of the workers are chosen at random to use Process 1 first, and the rest use Process 2 first. For each worker and each process, the assembly time (in minutes) is recorded, as shown in the table below.

Answer this question by performing a hypothesis test regarding Hd (which is μ with a letter "d" subscript), the population mean difference in assembly times for the two processes.…
Basketball players can take shots worth 3 points, 2 points, or 1 point. A scout is assessing two players- Tabitha and Lauren-who play for different teams in different leagues. The scout wonders if they have similar or different shot selections. They take a random sample of Tabitha's games and a separate random sample of Lauren's games. They tally how many of each type of shot the players attempted in those games. Here is a summary and the results of a chi-square test: Chi-square test: Shot vs. player Tabitha Lauren 3-point 8 12 Expected 10.34 9.66 2-point 40 37 Expected 39.83 37.17 1-point 12 Expected 9.83 9.17 x² = 2.097, DF = 2, P-value = 0.350 %3D Assume that all conditions for inference were met. At the a = 0.05 significance level, what is the most appropriate conclusion to draw from this test? Choose 1 answer: This is convincing evidence that the distribution of shot type differs between Tabitha and Lauren.
A survey was conducted in 1990 asking American high school students to name their favorite subject inschool. This survey found that, in 1990, the following proportions of students named each subject astheir favorite: 30% History, 25% Math, 20% English, 15% Biology, 10% Chemistry. A researcher in theyear 2020 conducts an identical survey, in order to see if students’ favorite subjects have shifted overthe 30 years that have passed since the 1990 study was done. The researcher gives the survey to n=60high school students, and gets the following observed frequencies and expected frequencies.

A manufacturing plant makes computer chips 24 hours a day. Employees work one of three, 8 hour shifts during the morning (2am-10am), day (10am-6pm), and night (6pm-2am). Below are data on the number of defective chips on a randomly chosen 24 hour period. Shift Morning Day Night Number of Defective Chips 23 26 47 Total Chips Manufactured 330 330 330 The plant manager thinks there might be more defective computer chips manufactured during the night shift compared to the day shift. Give appropriate statistical evidence to test the managers' claim.
Many golfers wear wrist bracelets containing magnets because they claim the magnets improve balance and the length of shots played off the tee. A golfer would like to determine if the claim has merit and finds 200 volunteers who play golf to participate in an experiment. Half of the golfers are randomly assigned to wear a bracelet with magnets, while the other half wear a bracelet without magnets. Each golfer plays normally for a month, after which the length of their shots in a subsequent round is recorded. What is the response variable in this experiment? the age of each golfer the 200 volunteers the length of shots played by the golfers whether the golfers wear or do not wear the bracelet
Red light! Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55% chance that the light will be red when he arrives at the intersection on a randomly selected workday. Suppose we choose 10 of Pedro's workdays at random and let Y = the number of times that the light is red. First, identify n= 10 and p = 1 Then plug them into the stapplet under Binomial distributions. 1. Find P(X 8) = P(Pedro gets exactly 8 red lights) = %3D 2. Find P(X 5) = P(Pedro gets more than 5 red lights) = a 9

Employees in the marketing department of a large regional restaurant chain are researching the amount of money that households in the region spend in restaurants per year. The employees are looking at how the amount spent annually in restaurants by households led by people ages 25 to 34 compares to households led by people ages 45 to 54. To conduct the research, the employees randomly select 100 households in the region led by people ages 25 to 34 and 100 households in the region led by people ages 45 to 54. Each household is asked how much was spent in restaurants during the previous 12 months. The amounts spent for each household, in dollars, are provided in the samples below. One household in each group spent $1,924 in restaurants during the previous 12 months. Use Excel to calculate the z-score for the data value that represents the household that spent $1,924 in restaurants for each group. Round your answers to two decimal places. Provide your answer below: 25 to 34 45 to 54…
