Does the order in which wine is presented make a difference? Several choices of wine are presented one at a time and in sequence, and the subject is then asked to choose the preferred wine at the end of the sequence. In this study, subjects were asked to taste two wine samples in sequence. Both samples given to a subject were the same wine, although subjects were expecting to taste two different samples of a particular variety Of the 32 subjects in the study, 22 selected the wine presented first, when presented with two identical wine samples.
(a) Show that the conditions for the large-sample confidence interval are not met.
(b) Are the conditions for the use of the plus four confidence interval met? If so, use the plus four method to give a 90% confidence interval for the proportion of subjects who would select the first choice presented. Interpret your interval.

Researchers presented a random sample of undergraduates with two test sheets, each sheet including 20 photos of the faces of dog‑owner pairs taken at a dog‑lovers field festival. The sets of dog‑owner pairs on the two sheets were equivalent with respect to breed, diversity of appearance, and gender of owners. On one sheet, the dogs were matched with their owners, while on the second sheet, the dogs and owners were deliberately mismatched. Students were asked to "choose the set of...

A group of researchers want to determine whether the order in which items are presented influences people’s responses. The researchers claimed to be test marketing a new laundry detergent and presented subjects with two identical freshly laundered towels. The subjects were asked feel each and state which one felt softer. In each pair of towels, one had been laundered using a bargain detergent while the other had been laundered using the same detergent and fabric softener so was noticeably softer....

Sulfur compounds cause "off‑odors" in wine, so winemakers want to know the odor threshold, the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25 micrograms per liter of wine (?g/L ). The untrained noses of consumers may be less sensitive, however. The DMS odor thresholds for 10 untrained students are given. 30 30 42 35 22 33 31 29 19 23 (a) Assume that...

An experiment on memory was performed, in which 16 subjects were randomly assigned to one of two groups, called "Sentences" or "Intentional". Each subject was given a list of 50 words. Subjects in the "Sentences" group were told to form multiple sentences, each using at least two words from the list, and to keep forming sentences until all the words were used at least once. Subjects in the "Intentional" group were told to spend five minutes memorizing as many of...

A debate rages whether or not bottled water is worth the cost. The National Resource Defense Council concludes, “there is no assurance that bottled water it is any cleaner or safer than tap (water).” But, in addition to the safety issue, many people prefer the taste of bottled water to tap water, or so they say! Let’s suppose that the city council members of Corvallis are trying to show that the city of Corvallis tap water tastes just as good...
