Hugo averages 58 words per minute on a typing test with a standard deviation of 11 words per minute. Suppose Hugo's words per minute on a typing test are normally distributed. Let X= the number of words per minute on a typing test. Then, X∼N(58,11). Suppose Hugo types 74 words per minute in a typing test on Wednesday. The z-score when x=74 is ________. This z-score tells you that x=74 is ________ standard deviations to the ________ (right/left) of the mean, ________.

For the 2015 Intel Science Fair, two brothers in high school recruited 47 of their classmates to take part in a two-stage study. Participants had to read two different passages and then answer questions on them, and each person's score was recorded for each of the two tests. There were no distractions for one of the passages, but participants received text messages while they read the other passage. Participants scored significantly worse when distracted by incoming texts. Participants were also asked if they thought they were good at multitasking (yes or no) but "even students who were confident of their abilities did just as poorly on the test while texting."1(a) How many cases are there?Entry field with correct answer(b) How many variables are mentioned in the description?Entry field with correct answerHow many of these are categorical?Entry field with incorrect answer now contains modified dataHow many are quantitative?Entry field with incorrect answer now contains modified data(c) If we created a dataset of the information with cases as rows and variables as columns, how many rows and how many columns would the dataset have?How many rows?Entry field with incorrect answer now contains modified dataHow many columns?

Problem 4-23 (Algorithmic) Suppose that you are given a decision situation with three possible states of nature: S1, S2, and S3. The prior probabilities are P(S1) = 0.20, P(S2) = 0.57, and P(S3) = 0.23. With sample information I, P(I | S1) = 0.12, P(I | S2) = 0.04, and P(I | S3) = 0.20. Compute the revised or posterior probabilities: P(S1 | I), P(S2 | I), and P(S3 | I). If required, round your answers to four decimal places.
