8. You know the minimum, the maximum, and the 25th, 50th, and 75th percentiles

of a distribution. Which of the following measures of central tendency or

variability can you determine?

mean, median, mode, trimean, geometric mean, range, interquartile range,

variance, standard deviation

9. For the numbers 1, 3, 4, 6, and 12:

Find the value (v) for which (X-v)2 is minimized.

Find the value (v) for which |x-v| is minimized.

10. Your younger brother comes home one day after taking a science test. He says

that some- one at school told him that "60% of the students in the class scored

above the median test grade." What is wrong with this statement? What if he had

said "60% of the students scored below the mean?

In case having a shirt number from one to 33 and gauging everything considered 210 pounds were self-sufficient events, by then what should be legitimate about P(Shirt# 1-33| 210 pounds)?

The probability that a male cultivates some kind of harm throughout his life is 0.4567. The probability that a male has in any occasion one sham positive test result (which implies the test returns for threat when the man doesn't have it) is 0.51. A bit of the going with requests need more information for you to react to them. Express "deficient information" for those answers. Let C = a man makes infection over the span of his life and P = man has at any rate one false sure.

P(C) = ______

P(P|C) = ______

P(P|C') = ______

In case a test comes up sure, considering numerical characteristics, would you have the option to expect that man has harmful development? Legitimize numerically and explain why or why not.

A sack of marbles contains 4 red marbles and 6 blue marbles. Consider the test where 3 marbles are browsed the pack and a while later a standard 6-sided pass on is rolled.

(a) Consider the model space S for the test, what is n(S)? Note: The solicitation for the three picked marbles doesn't have any effect.

(b) Consider the event E that all the marbles picked were blue. What is the probability of E?

(generously explain where the characteristics used to discover (b) came from!)

(F) What is the 95% confidence interval of the mean time people wait before

farting in front of a romantic partner.

Animal Research (AR) case study

29. (AR) What percentage of the women studied in this sample strongly agreed

(gave a rating of 7) that using animals for research is wrong?

30. (AR) Use the proportion you computed in #29. Compute the 95% confidence

interval on the population proportion of women who strongly agree that animal

research is wrong.

31. (AR) Compute a 95% confidence interval on the difference between the gender

means with respect to their beliefs that animal research is wrong.

ADHD Treatment (AT) case study

32. (AT) What is the correlation between the participants' correct number of

responses after taking the placebo and their correct number of responses after

taking 0.60 mg/kg of MPH? Compute the 95% confidence interval on the

population correlation.

Weapons and Aggression (WA) case study

33. (WA) Recall that the hypothesis is that a person can name an aggressive word

more quickly if it is preceded by a weapon word prime than if it is preceded by

a neutral word prime. The first step in testing this hypothesis is to compute the

difference between (a) the naming time of aggressive words when preceded by

a neutral word prime and (b) the naming time of aggressive words when

preceded by a weapon word prime separately for each of the 32 participants.

That is, compute an - aw for each participant.

a. (WA) Would the hypothesis of this study be supported if the difference were

positive or if it were negative?

b. What is the mean of this difference score?

c. What is the standard deviation of this difference score?

d. What is the 95% confidence interval of the mean difference score?

4 (5 points). In a certain college, 25% of the students failed Mathematics(M), 15%% failed Computer science (C), and 40 %% that a student fail computer science given that the student failed mathematics. A student is selected at random 1. Find the probability that he failed both mathematics and computer science. 2. If he failed computer science, find the probability that he also failed math. 3. Find the probability that he failed mathematics or computer science. 4. Find the probability that he failed mither mathematics nor chemistry.Question: At a liberal arts college, 90% of the freshmen are enrolled in English 105, 80% are enrolled in Mathematics 101 and 5% are enrolled in Mathematics 101 but not in English 105. A freshman is randomly selected. a. What is the probability that the freshman is enrolled in both English 105 and Mathematics 101? b. What is the probability that the freshman is enrolled in English 105 but not in Mathematics 101? c. Suppose the freshman chosen is known to be enrolled in Mathematics 101. What is the probability that the freshman is also enrolled in English 105? P(E) = 0.90 P(M) = 0.80 m M P(MnE ) = 0.05 P(EnM') = 0.15 P(MnE) = 0.75Quiz: Quiz 4 - Chapters 4.3-4.5 & 20 Time Remaining: 00:54:49 Submit Quiz This Question: 4 pts 23 of 29 This Quiz: 50 pts possible ading Question Help Quantity of ading Quantity of Subscriptions to Subscriptions to Office Economics Statistics Apps Productivity Apps per per Year Total Utility (utils) Year Total Utility (utils) 400 700 850 950 1,000 1.025 Refer to the above table and assume that each year this consumer buys only annual subscriptions to economics statistics apps and subscriptions to office productivity apps. The price of a subscription to each type of economics statistics app is $3, and the subscription to each office productivity app is $60 per year. If the consumer's available income is $255 per year, the consumer will purchase ]economics statistics app(s) and office productivity app(s). If the consumer's available income falls to $66, what will be the new combination of economics statistics apps and office productivity apps? economics statistics app(s): and office productivity app(s): 20.5 Deme Enter your answer in each of the answer boxes.
