The County Clerk in Essex, New Jersey, was accused of cheating by not using randomness in assigning the order in which candidates’ names appeared on voting ballots. Among 41 different ballots, Democrats were assigned the desirable first line 40 times. Assume that Democrats and Republicans are assigned the first line using a method of random selection so that they are equally likely to get that first line.

Which probability is relevant for determining whether 40 first lines for Democrats is significantly high: the probability from part (b) or part (c)? Based on the relevant probability, is the result of 40 first lines for Democrats significantly high?

The County Clerk in Essex, New Jersey, was accused of cheating by not using randomness in assign ing line positions on voting ballots. Among 4 l different ballots, Democrats were assigned the top line 40 times. Assume that Democrats and Republicans are assigned the top line using a method of random selection so that they are equally likely to get that top line. Find the probability of 40 or more top lines for Democrats.

The County Clerk in Essex, New Jersey, was accused of cheating by not using randomness in assign ing line positions on voting ballots. Among 4 l different ballots, Democrats were assigned the top line 40 times. Assume that Democrats and Republicans are assigned the top line using a method of random selection so that they are equally likely to get that top line. Use the range rule of thumb to identify the limits separating values that are significantly low and those that are significantly high. Based on the results, is the result of 40 top lines for Democrats significantly high?

Determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

In a study of the Ornish weight loss program, 40 subjects lost a mean of 3.3 lb after 12 months (based on data from “Comparison of the Atkins, Ornish, Weight Watchers, and Zone Diets for Weight Loss and Heart Disease Risk Reduction,” by Dansinger et al., Journal of the American Medical Association, Vol. 293, No. 1). Methods of statistics can be used to show that if this diet had no effect, the likelihood of getting these results is roughly 3 chances in 1000.

Identify which of these designs is most appropriate for the given experiment: completely randomized design, randomized block design, or matched pairs design.Lunesta is a drug designed to treat insomnia. In a clinical trial ofLunesta, amounts of sleep each night are measured before and after subjects have been treated with the drug.

Identify which of these types of sampling is used: random, systematic, convenience, stratified, or cluster. Cormorant bird population densities were studied by using the "line transect method" with aircraft observers flying along the shoreline of Lake Huron and collecting sample data at intervals of every 20 km (based on data from Journal of Great Lakes Research).

Identify whether the given value is a statistic or a parameter.

A survey of a sample of consumers in the United States showed that among those who have found a wallet or purse, 89% either turned it in or located the owner (based on a Toluna Quicksurveys poll).

In a Citrix Security survey of 1001 adults in the United States, it was found that 69% of those surveyed believe that having their personal information stolen is inevitable. Identify the population and sample. Is the value of 69% a statistic or a parameter?

Among 4 l different ballots, Democrats were assigned the top line 40 times. Assume that Democrats and Republicans are assigned the top line using a method of random selection so that they are equally likely to get that top line. Find the probability of exactly 40 top lines for Democrats.

From 100 M&M candies, 19 of them are green. Mars, Inc. claims that 16% of its plain M&M candies are green. For the following, assume that the claim of 16% is true, and assume that a sample consists of 100 M&Ms. What do the results suggest about the 16% claim by Mars, Inc.?

Data Set 38 “Candies” in Appendix B includes data from 345 M&M candies, and 36 of them are brown. Mars, Inc. claims that 13% of its plain M&M candies are brown. For the following, assume that the claim of 13% is true, and assume that a sample consists of 345 M&Ms.
