2. A meeting of consuls was attended by 4 Americans and 2 Germans. If three Consuis were selectedat random one after the other, determine the values of the random variable G representing thenumber of Germans. (to list the sample space use A, A2, As, A. for the 4 Americans and G., G2 forthe 2 Germans)Step 1. List the sample space of this experiment.S= -Step 2.Count the number of GermansOutcomeNumber of Germans (Value of G)

Given Information: Number of Americans = 4 Number of Germans = 2 Total number of consuls = 4+2 =6

Employers want to know which days of the week employees are absent in a five-day workweek. Most employers would like to believe that employees are absent equally during the week. Suppose a random sample of managers were asked which day of the week they had the highest number of employee absences. The results were distributed as follows: The number of Absences on Monday was 17 The number of Absences on Tuesday was 17 The number of Absences on Wednesday was 4 The number of Absences on Thursday was 6 The number of Absences on Friday was 11 What is the Test Statistic to test the Hull Hypothesis that The absent days occur with equal frequencies (that is, they fit a uniform distribution) against the alternative Hypothesis that the absent days occur with unequal frequencies (that is, they do not fit a uniform distribution)?
58% of all statistics classes require a statistical calculator and 30% require the use of a computer that has statistical software. Of the classes that require a statistical calculator, 16% also require the use of a computer. If a statistics course is selected at random find: (round to 4 decimal places where possible) a. P(Statistical Calculator) = b. P(Statistical Software) = c. P(Require a Statistical Calculator and Statistical Software) = d. P(Require a Statistical Calculator GIVEN Require Statistical Software) =
Suppose that Mairin has knit a collection of wool‑blend infinity scarves that she wants to sell in her Etsy shop for $28.00 each. However, she is worried that if the average price of comparable scarves is less than $28.00, hers would be less likely to sell. Mairin selected a random sample of 9 similar hand‑knit, wool‑blend infinity scarves, and their prices are as follows. $21.75,$24.00,$27.25,$29.95,$23.00,$26.00,$27.80,$33.50,$27.00$21.75,$24.00,$27.25,$29.95,$23.00,$26.00,$27.80,$33.50,$27.00 Use a left‑tailed one‑sample ?t‑test to determine whether the average price of hand‑knit, wool‑blend infinity scarves sold on Etsy is less than $28.00. Assume that the prices of all comparable scarves are normally distributed. Mairin should (reject, accept, fail to accept) her null hypothesis. There is (sufficient, no, insufficient) evidence that the mean price of hand‑knit, wool‑blend infinity scarves is (greater than, different from, less than, equal two) $28.00.
A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 210 people who snore participating in the experiment. Using a table of random digits starting from the first row and column, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison. Which number range would be needed to label the subjects correctly? O 0-2 O 1-3 O 000-210 O 001-210
Suppose you rolled a fair six-sided die a few times and recorded the results. (You would have a collection of numbers 1-6.) Now, suppose you wanted to average these numbers. What value would you expect? If the die was rolled 6 times and the results were: 1, 4, 2, 2, 3, 2, then the average of this sample of rolls would be 2.333. This experiment could be peformed again: 6, 5, 2, 1, 1, 4. Now, the average of this sample is 3.167. Obviously, these small samples have a lot of variation in them; however, is there a way to calculate the expected average? If we were to construct a very large sample, rolling this die 1 million times, what would the expected value (mean) be? Luckily, the rules of probability allows us to do this calculation without actually having to roll the die 1 million times! Below, you will find a probability table where all of the possible outcomes from the die are listed. The first column contains the possible outcomes on the die, the second column contains the…
Please help. Suppose we roll a regular six die three times.

A government official is in charge of allocating social programs throughout the city of Vancouver. He will decide where these social outreach programs shoulde located based on the percentage of residents living below the poverty line in each region of the city. He takes a simple random sample of 130 people living in Gastown and finds that 21 have an annual income that is below the poverty line. Part i) The proportion of the 130 people who are living below the poverty line, 21/130, is a: A. parameter. B. statistic. C. variable of interest. Part ii) Use the sample data to compute a 95% confidence interval for the true proportion of Gastown residents living below the poverty line. (Please carry answers to at least six decimal places in intermediate steps. Give your final answer to the nearest three decimal places). 00 95% confidence interval=
