  1. Suppose this is your data-> 0,0,1,2,3,4,5,6,7.
    1. Calculate the 3rd quartile from your data.
    2. What's the probability that a randomly selected number is even? Note: 0 counts as an even number.
    3. Consider the events A = "a randomly selected number from your data is even" and B = "a randomly selected number from your data is above the 3rd quartile". Are these events disjoint, independent, neither, or both? Show your work.

Answer #1

The probability that a selected number is even is, 0.55

The probability that a selected number is above 3rd quartile is 0.22

Since intersection of two events A and B is not a null set, therefore A and B are not disjoint events.

Occurence of event A does not affect occurence of event B, therefore events A and B are independent events.

Census data for a certain county show that 19% of the adult residents are Hispanic. Suppose 72 people are called for jury duty and only 9 of them are Hispanic. Does this apparent under-representation of Hispanics call in to question the fairness of the jury selection system? Explain a) Using the given Binomial model: Find the probability of falling at least as far away from expected as we actually observed, meaning 4.68 or more away from 13.68 (in either direction)....

According to data from the Tobacco Institute Testing Laboratory, a certain brand of cigarette contains an average of 1.4 milligrams of nicotine. An advocacy group questions this figure, and commissions an independent test to see if the the mean nicotine content is higher than the industry laboratory claims. The test involved randomly selecting ?=15n=15 cigarettes, measuring the nicotine content (in milligrams) of each cigarette. The data is given below: 1.7,1.6,1.8,2.0,1.4,1.4,1.9,1.6,1.3,1.5,1.2,1.4,1.7,1.2,1.5 (a) State null and alternative hypothesis. (b) Obtain critical value...
