1. A Game Three understudies are playing a game. They choose to pick the principal individual to play by each choosing a card from the 52-card deck and searching for the most elevated card in worth and suit. They rank the suits from most minimal to most noteworthy: clubs, precious stones, hearts, and spades. a. On the off chance that the card is supplanted in the deck after every understudy picks, what number of potential setups of the three decisions are conceivable?

b. What number of designs are there in which every understudy picks an alternate card? c. What is the likelihood that every one of the three understudies pick the very same card? d. What is the likelihood that every one of the three understudies pick various cards?

Question 13 The Mann-Whitney and the Wilcoxon tests are both used to compare the means of Not yet answered Two populations. Which of these should be used if the samples are related? Marked out of 1.00 Flat question Select one: a. Wilcoxon b Mann-Whitney "C neither d. . both of these may be used Previous page MAT1114 - Statistics trimester 1 2019 Jump to Alternative A exam and solutionsConsider the following hypothesis for a Wilcoxon signed rank test. Ho : m = 6 versus H, : m # 6 where m is the mean of the underlying population. a) Determine the p-value of the Wilcoxon signed rank test using the data: X1 = 15, 12 = 7, 13 = 3, 4 = 10, x5 = 13. Show all your calculations clearly. b) Use the Wilcoxon test in R to generate the p-value and compare with the result obtained in part (a).3. [10 marks] Data on the one-year returns for a sample of financial sector equity funds are displayed below as percentages. We are interested in whether the typical return is positive. One-year returns (%): 4.64 1.37 3.15 3.39 -.47 1.7 -2.81 5.14 2.97 -0.17 (a) Explain whether a parametric test or a non-parametric test is more appropriate (b) Perform a Wilcoxon test manually to see if the median return for all financial services equity funds is indeed positive. Find the appropriate Wilcoxon critical value for the 0.05 level of significance. (c) Use the large-sample version of the Wilcoxon test to calculate a z-statistic for your result. What is the p-value? (d) Do the test on Minitab. How do the Minitab results support the earlier results in (b) and (c)?100 .
