- If, in a given sample space, P (A) = 0.6, P (B) = 0.40, and P (A and B) = 0.20, then the value of P (A or B) will beThe Psychic Friends Network (PFN) received telephone calls in 1999 from over 1.5 million people. A journal article attempted to shed some light onto the credibility of the PFN. One of the psychic friends' psychics agreed to take part in the following experiment. 10 cards are shown to the "psychic" then shuffled, and one is chosen at random. The psychic will then try to identify which card was drawn without seeing it. Assume that the experiment was repeated 15 times and that the results of any two experiments are independent of one another. Step 1 of 4: If we assume that the psychic is a fake (i.e, they are merely guessing at the cards and have no psychic powers), how many of the 15 cards do we expect the psychic to guess correctly? (Round your answer to the nearest integer)Wal-Mart wants to introduce a new subscription service (called Plum) that would result in customers getting free two-day delivery. Wal-Mart introduces Wal-Mart Plum to a random sample of 99 customers. You are hired by Wal-Mart to analyze if the introduction of Plum andtwo-day delivery increases sales for Wal-Mart. You find that the 99 random customers that were offered Plum Two Day Delivery spent $2,500 per year on Wal-Mart with a sample standard deviation of $500 in sales. (A) Test whether the sales of Wal-Mart Plum are statistically different from zero at an alpha of 1% (99% confidence level). Set up your null and alternative hypotheses. Test at the 1% level of significance. Show your test and critical statistics. Are the sales for Two-Hour Plum Delivery statistically different from 0? Interpret your answer. Show your work (B) Suppose the typical Wal-Mart consumer spends $2000 a year. Test whether the introductionof Wal-Mart Plum Delivery increased sales. Set up your null and…
- A marketing agency wanted to determine if a new commercial changed people's opinion about a company. They recruited n=30 participants to watch the commercial. First, everyone was givien a survey to determine their attitudes toward the company. Then, everyone watched the new commercial. Finally, they were given the same survey again and asked about their attitudes toward the comapny after seeing the commercial. The agency wanted to see if attitudes were changed by the commercial. What statistical test should they use?1Determine the size of the sample space of the following experiment. A lottery drawing consists of 5 randomly drawn numbers from 1 to 11; the order of the numbers matters in this case, and repetition is possible.

- The proportion of brown M&M's in a milk chocolate packet is approximately 14%. Suppose a package of M&M's typically contains 57 M&M's. a) State the random variable. b) List the given numbers with correct symbols. = 57 = 0.14 c) Explain why this is a binomial experiment. Check all that apply. There are more than two outcomes for each M&M There are a fixed number of M&Ms, 57 Whether or not one randomly selected M&M is brown will not affect whether or not another randomly selected M&M is brown There is not a fixed number of M&Ms There are only two outcomes for each M&M p = 14% remains constant from one randomly selected M&M to another Whether or not one randomly selected M&M is brown will affect whether or not another randomly selected M&M is brown Find the probability, to 4 decimal places: It is possible when rounded that a probability is 0.0000 d) exactly none are brown. e) exactly 54 are brown. f) at least…A sports arena has three entrances (E1, E2, E3) and four different exits (X1, X2, X3, X4).
