Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected and the alcohol content of each bottle is determined. Let u denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (7.1, 9.8). (a) Would a 90% confidence interval calculated from this same sample have been narrower or wider than the given interval? Explain your reasoning. The 90% would be wider...

A random sample of 50 bottles of a brand of cough syrup is selected, the alcohol content of each bottle is calculated Let μ be the average alcohol content for the population of all bottles of the brand under consideration. The resulting 95% confidence interval is (7.8,9.4) (a) Would a 90% confidence interval calculated from the same sample be wider or narrower? Explain. (b) Consider the statement: there is a 95% chance that is between 7.8 and 9.4. Is this correct? Explain. (c)...

Suppose that a random sample of 50 bottles of a particular brand of cough syrup is selected, and the alcohol content of each bottle is determined. Let μ denote the average alcohol content for the population of all bottles of the brand under study. Suppose that the resulting 95% confidence interval is (8.0, 9.6).a. Would a \(90 \%\) confidence interval calculated from this same sample have been narrower or wider than the given interval? Explain your reasoning.b. Consider the following statement:...

Suppose a random sample of 50 bottles of "CoughGone" cough syrup was collected and the alcohol content (in wt. percent) of each bottle measured. A 95 % confidence interval for bottle true mean alcohol content, μ, was then determined from these data to be (6.7, 9.3). It was assumed that the variance of the alcohol distribution was known. a.) What is the value of the sample mean, x̄ ?(Give answer to two places past decimal.) b.) What is the value...

You work for a pharmaceutical company wanting to make a new flavor of cough syrup. You are asked to conduct research on flavor preferences. You would like to know whether people like Cherry Lime, Vanilla Mint and Cinnamon Mocha flavors differently. You divided all potential customers into geological regions and randomly selected a few regions to recruit your study participants from. Then from the selected regions, your randomly recruited 24 participants, which is representative of all potential customers of your...
