Question 8 D A researcher's hypothesis is that the average length of salmon returning to spawn from an Alaskan river is less than the historical average length of 24 inches. The researcher collects a random sample of 45 salmon, measures the length of each fish, and computes an average length of 22 inches, with a standard deviation of 3.1 inches. Which of the following is the appropriate test for the researcher's hypothesis? A matched-pairs t-test for a mean difference B A two-sample t-test for a difference between means A one-sample z-test for a population mean A one-sample t-test for a population mean A one-sample z-test for a population proportion

The average and standard deviation of the amount of GST paid by all sole trader businesses in Australia in a twelve month period were $5.602 thousand and $1.637 thousand respectively. If a sample of 120 sole trader businesses was chosen, find the sample average value above which only 15% of sample averages would lie. Give your answer in dollars (to the nearest dollar).

You hope to rent an unfurnished one-bedroom apartment in Dallas next year. You call a friend who lives there and ask him to give you an estimate of the mean monthly rate. Having recently taken a statistics course, your geeky friend asks about the desired margin of error and confidence level for the estimate. He also tells you that the standard deviation of monthly rents for one-bedrooms is $360. Explain why in either case your geeky friend's sample may result in a bigger margin of error than desired. A bigger margin of error might result due to O rounding O a smaller guessed value for the population standard deviation sg O smaller confidence interval O a larger sample size
Consider the following data: −11,−5,−5,−11,13,−11,−5−11,−5,−5,−11,13,−11,−5 Copy Data Step 2 of 3: Calculate the value of the sample standard deviation. Round your answer to one decimal place.
A film distribution manager calculates that 9% of the films released are flops. If the manager is right, what is the probability that the proportion of flops in a sample of 506 released films would differ from the population proportion by greater than 3%? Round your answer to four decimal places.
During an evolution, the minimum, maximum, and average fitness of a population is 1.2, 270, and 40, respectively. If the most fit individual is to be 3 time more likely than the average fit individual to be selected, and the least fit individual is 1/3 as likely as the average fit individual to be selected, what is the scaled fitness of an individual whose raw fitness is 58.
Refer to the sample data for polygraph tests shown below. If one of the test subjects is randomly selected, what is the probability that the subject is not lying? Is the result close to the probability of 0.490 for a negative test result? Consider the result close if the absolute difference is less than 0.050. Did the Subject Actually Lie? No (Did Not Lie) 10 33 Positive test results Negative test results Yes (Lied) 39 14 C The probability that a randomly selected polygraph test subject was not lying is (Type an integer or decimal rounded to three decimal places as needed.) Is the result close to the probability, rounded to three decimal places, of 0.490 for a negative test result? Consider the result close if the absolute difference is less than 0.050. because there is a 0.050 absolute difference between the probability of a true response and the probability of a negative test result.
Scenario 38-5. Researchers are interested in the height of the average person in San Francisco, California. Using a random sample of 1,000 people, they find that the average height in the sample is 68 inches. (Hint: Be sure to calculate the Refer to Scenario 38-5. If the standard deviation of heights is 3 inches, we can be 95% confident that the true mean height of the population is between standard error of the estimate.) O O O O between 67.997 inches and 68.003 inches. between 67.905 inches and 68.095 inches. between 67.905 inches and 68 inches. between 68 inches and 68.095 inches.

Suppose it is known that in a certain large human population cranial length is approximately normally distributed with a mean of 185.6 mm and a standard deviation of 12.7 mm. A random sample of size 10 from this population will have a mean greater than 190 with a=0.05 ? let Z-tabulate = 1.96 and T-tabulate= 2.30
