From a sample with n=36, the mean duration of a geyser's eruptions is 3.06 minutes and the standard deviation is 0.85 minutes. Using Chebychev's Theorem, determine at least how many of the eruptions lasted between 1.36 and 4.76 minutes. At least of the eruptions lasted between 1.36 and 4.76 minutes. (Simplify your answer.)

Harper's Index reported that 80% of all supermarket prices end in the digit 9 or 5. Suppose you check a random sample of 112 items in a supermarket and find that 87 have prices that end in 9 or 5. Does this indicate that fewer than 80% of the prices in the store end in the digits 9 or 5? Use α = 0.05. 1. What is the value of the sample test statistic? (Round your answer to two decimal places.) 2. Find the P-value of the test statistic. (Round your answer to four decimal places.)

MY NOTES In a random survey of 221 self-employed individuals, 22 reported having had their tax returns audited by the IRS in the past year. Estimate the proportion of self-employed individuals nationwide who have been audited by the IRS in the past year.(a) Find the 95% confidence interval for the true proportion of self-employed individuals nationwide who have been audited by the IRS in the past year: ( , ) (Use 4 decimals.) (b) Are the conditions for inference met? Yes, because 221 > 30.Yes, because 221(0.5) > 30. Yes, because 221(0.0995) > 10 and 221(1 − 0.0995) > 10.We don't have enough information. It's possible the data are not Normally distributed, so we should proceed with caution. (c) How should this interval be interpreted? We are 95% confident that the percent of self-employed individuals nationwide who have been audited by the IRS in the past year is 10.0%.We are 95% confident that a randomly chosen self-employed individual who have been audited by…
