An individual is presented with three different glasses of cola, labeled C, D, and P. He is asked to taste all three and then list them in order of preference. Suppose the same cola has actually been put into all three glasses. (a) What are the simple events in this ranking experiment? (Enter your answer in set notation.) (CDP.CPD.DCP.DPC.PCD.PDC} What probability would you assign to each one? O The probability of an individual event where D is ranked first is 1 The probability of another individual event is 15 O The probability of an individual event where D is ranked first is . The probability of another individual event is 12 4 O It is impossible to determine the probability of the simple events with the given information. O All of the simple events have the same probability, 6 O All of the simple events have the same probability, (b) What is the probability that C is ranked first? (Round your answer to three decimal places.) 0.166 (c) What is the probability that C is ranked first and D is ranked last? (Round your answer to three decimal places.) 3:40 PM ENG 2/3/2022 DELL

sorry I should of been clear, I need letter B to be worked out.

A marketing firm wishes to test the effectiveness of the audio/visual presentation of certain information as opposed to the purely audio presentation of the information.  To this end 100 volunteers were given a 10 minute presentation in which the information was presented in an audio/visual format.  A second group of 100 volunteers was presented the same information in a purely audio format.  Each person in each of the two groups was asked the same 20 questions related to the information in the presentation.   The audio/visual group had an average of 10.5 correct responses with a sample standard deviation of 4.  The purely audio group had an average of 9.4 correct responses with a standard deviation of 3.  The marketing firm believes this means that the audio/visual format leads to better retention of the information. We test the hypotheses H0:  1 -2=0 versus Ha: 1 -2>0 at a 2% level of significance.   Here  denotes  1 the population average number of correct responses for…

Is there any way I can get this written by hand? It's hard to read, but I'm attempting to grasp it.

what is the final answer to this question

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…

During his short stint as Shadow Finance Minister, Barnaby Joyce displayed a curious grasp of numbers. One of his most infamous exclamations was “All this billions, quillions, Brazilians.” Less well known was his tax-reform proposal, recommending that if you earn $x per day, you are taxed x% of that amount (with the understanding that you pay 100% tax if you earn $100 or more per day. Under Senator Barnaby’s plan, which amount x gives you the highest earnings after tax has been taken out?
