The weather on any given day in a particular city can be sunny, cloudy, or rainy. It has been observed to be predictable largely on the basis of the weather on the previous day Specficallyif it is sunny on one day, it will be sunny the next day 1/2 of the time, and be cloudy the next day 1/10 of the timeif it is cloudy on one day, it will be sunny the next day 1/10 of the time, and be cloudy the next day 7/10 of the timeif it is rainy on one day, it will be sunny the next day 2/5 of the time, and be cloudy the next day 1/5 of the time.Using 'sunny', 'cloudy', and 'rainy' (in that order) as the states in a system, set up the transition matrix for a Markov chain to describe this system.Find the proportion of days that have each type of weather in the long run000P=000000SunnyProportion of days that are CloudyRainy00

QUESTION 1 Smokers at a company were invited to participate in a smoking cessation program, and were randomly assigned to one of two groups. Those in the Reward group would get a cash award if they stopped smoking for 6 months. Those in the Deposit group were asked to deposit some money which they would get back along with a substantial bonus if they stopped smoking for 6 months. After six months, 156 of the 914 smokers who accepted the invitation to be in the reward-only program stopped smoking, while 78 of the 146 smokers who paid a deposit quit. A two-way table for this data is given below. (Be careful: "Total" rows/columns are not included.) Quit Smoking Yes No Treatment Group Reward 156 758 Deposit 78 68 Use this table to answer Problems 1-4. 1) How many people in the study had quit smoking after six months? Calculate the difference in proportion who quit smoking, , between those in the Deposit program and those…
This problem set deals with the problem of non-constant acceleration. Two researchers from Fly By Night Industries conduct an experiment with a sports car on a test track. While one is driving the car, the other will look at the speedometer and record the speed of the car at one- second intervals. Now, these aren't official researchers and this isn't an official test track, so the speeds are in miles per hour using an analog speedometer. The data set they create is: {(1,5), (2, 2), (3, 30), (4, 50), (5, 65), (6,70)} Z = 25 They notice that the acceleration is not a constant value. They decide that a fourth-degree polynomial will be the best to describe the speed of the car as a function of time. The task here is to determine the fourth-degree polynomial that fits this data set the best. 1. Construct the system of normal equations A¹ Ax = A¹b. AT A = АТЬ= 2. Solve the system of normal equations. (I don't want you doing this by hand. Use a calculator or app.) x =
question 28. I will submit this problem in three parts because it is long, and i was asked to seperate longer problems so you are not asked to do more than what you are being paid for. part 1 problem #28 Before the furniture store began its ad campaign, it averaged 146 customers per day. The manager is investigating if the average is larger since the ad came out. The data for the 16 randomly selected days since the ad campaign began is shown below: 172, 147, 168, 163, 166, 139, 158, 151, 137, 140, 138, 137, 158, 133, 144, 144 Assuming that the distribution is normal, what can be concluded at the αα = 0.10 level of significance? A.)For this study, we should use Select an answer t-test for a population mean z-test for a population proportion B.)The null and alternative hypotheses would be: H0:H0: ? p μ Select an answer < = ≠ > H1:H1: ? μ p Select an answer > < ≠ = C.)The test statistic ? z or t = ____ (please show your answer to 3 decimal places.)

1. Pretend that in a certain city the number of new cases of COVID was reported to be 200 new cases on Sunday. Let’s pretend that the number of new cases grows by 22% on Monday, and then after that falls by 22% on Tuesday Question C: What percent would the percent increase have to be on Monday to have a total change of zero% from Sunday to Tuesday? i.e. new covid cases go up by ???% on Monday and then down 22% on Tuesday for a total change of 0%. (Use decimals in answer if needed)
QUESTION 1 At Snead State Community College, students earn four quality points per semester hour for each A, three quality points per semester hour for each B, two quality points per semester hour for each C, and one quality point per semester hour for each D, while F's earn zero quality points. If a student has earned 21 semester hours of A's, 18 semester hours of B's, 18 semester hours of C's, 3 semester hours of D's and 9 semester hours of F's, what is his/her GPA?

Question No. 04: GfK Research North America conducted identical surveys 5 years apart. One question asked of women was “Are most men basically kind, gentle, and thoughtful?” The earlier survey revealed that, of the 3,000 women surveyed, 2,010 said that they were. The later revealed 1,530 of the 3,000 women surveyed thought that men were kind, gentle, and thoughtful. At the .05 level, can we conclude that women think men are less kind, gentle, and thoughtful in the later survey compared with the earlier one?
