Lady tasting tea A famous (in statistical circles) study involves a woman who claimed to be able to tell whether tea or milk was poured first into a cup. She was presented with eight cups containing a mixture of tea and milk, and she correctly identified which had been poured first for all eight cups. 1.1.12 a. Identify the observational units and variable in this study. b. Identify the parameter for this study. (Hint: The long-run proportion that...) c. Identify the sample size. Also, identify the observed value of the statistic for this study. d. Is it possible that the woman could get all eight correct if she were randomly guessing with each cup? e. Is it unlikely that the woman could get all eight correct if she were randomly guessing with each cup? (Answer for now based on your intuition, without doing any analysis.)

7. An experiment compares the taste of instant with fresh-brewed coffee. Each subject tastes two unmarked cups of coffee, one of each type, in random order and states which he or she prefers. Of the 60 subject sample who participate in the study, 21 prefer the instant coffee. Let p be the probability that a randomly chosen subject prefers fresh-brewed coffee. (In practical terms, p is the proportion of the population who prefer fresh-brewed coffee.) Test the claim that a majority of people (p > 0.5) prefer the taste of fresh-brewed coffee. HINT: The sample proportion can be found from the sample information above. The mean μ p ^ and standard deviation σ p ^ of the distribution can be found using p = 0.5 and n = 60. Report the z-statistic to 2 decimal places. Draw a sketch of the standard Normal curve and mark the location of your z-statistic. Shade the appropriate area that corresponds to the p-value. (do not need to turn in) What is the proportion of sample proportions that are above the z score you found? (report to 2 decimal places) Then, determine if it is probable to find a sample proportion of 39/60 who prefer fresh-brewed coffee or greater? Use a cut-off of 0.05: probability > 0.05 is probable, probability ≤ 0.05 is not probable.

Read each brief report of statistical research, and identify a) whether it was an observational study or an experiment. If it was an observational study, identify (if possible) b) whether it was retrospective or prospective. c) the subjects studied and how they were selected. d) the parameter of interest. e) the nature and scope of the conclusion the study can reach. If it was an experiment, identify (if possible) b) the subjects studied. c) the factor(s) in the experiment and the number of levels for each. e) the response variable measured. f) the design (completely randomized, blocked, or matched). g) whether it was blind (or double-blind). h) the nature and scope of the conclusion the experiment can reach. Is diet or exercise effective in combating insomnia? Some believe that cutting out desserts can help alleviate the problem, while others recommend exercise. Forty volunteers suffering from insomnia agreed to participate in a month-long test. Half were randomly assigned to a special no-desserts diet; the others continued desserts as usual. Half of the people in each of these groups were randomly assigned to an exercise program, while the others did not exercise. Those who ate no desserts and engaged in exercise showed the most improvement.
A consumer group claims that the mean annual consumption of coffee by a person in the U.S. is 23.2 gallons. A random sample of 90 people in the U.S. has a mean annual coffee consumption of 21.6 gallons. Assume the population standard deviation is 4.8 gallons. At a=0.05, can you reject the claim? A) Write the claim mathematically and state the null and alternative hypotheses. B) Determine whether the hypothesis test is left-tailed, right-tailed, or two tailed and whether to use a z-test, a t-test, or a chi-square test. Explain your reasoning. C) Find the critical value(s), draw a sketch identifying the rejection region(s). D) Find the appropriate standardized test statistic. E) Decide whether to reject or fail to reject the null hypothesis. F) Interpret the decision in the context of the original claim.
