In a certain election, 49% of the women voters voted for
Candidate A, while only 48% of men voters voted for Candidate A. An
exit poll of 234 women and 194 men was conducted. Let
[^(p)]1 and [^(p)]2 denote
sample proportions of women and men voters respectively who voted
for Candidate A.
Answer all the questions below (where appropriate) as a
fraction not as a percentage.
What is the expected value of [^(p)]1? [Answer to two decimal places.]

What is the standard deviation of [^(p)]1? [Answer to four decimal places.]

What is the expected value of [^(p)]2? [Answer to two decimal places.]

What is the expected value of [^(p)]1 − [^(p)]2? [Answer to two decimal places.]
| Tries 0/5 |
What is the standard deviation of [^(p)]1 − [^(p)]2? [Answer to four decimal places.]

English belongs to the Indo-European family of languages and is therefore related to most other languages spoken in Europe and western Asia from Iceland to India. The parent tongue, called Proto-Indo-European, was spoken about 5,000 years ago by nomads believed to have roamed the southeast European plains. Germanic, one of the language groups descended from this ancestral speech, is usually divided by scholars into three regional groups: East (Burgundian, Vandal, and Gothic, all extinct), North (Icelandic, Faroese, Norwegian, Swedish, and Danish), and West (German, Dutch [and Flemish], Frisian, and English). Though closely related to English, German remains far more conservative than English in its retention of a fairly elaborate system of inflections. Frisian, spoken by the inhabitants of the Dutch province of Friesland and the islands off the west coast of Schleswig, is the language most nearly related to Modern English. Icelandic, which has changed little over the last thousand years, is the living language most nearly resembling Old English in grammatical structure.

An exit poll at an election of 1000 voters shows that 540 voted for Homer Simpson. Of course, Homer is guaranteed to win the election if more than half of the population voted for him (or the population proportion p> 0.5). Can Homer claim victory at the 0.05 level of significance? What is the p-value of the test statistic? (9 points)

In an election, suppose that 35% of voters support creating a new fire district. If we poll 166 of these voters at random, the probability distribution for the proportion of the polled voters that support creating a new fire district can be modeled by the normal distribution pictured below. The marks on the horizontal axis show 0, +1, -1, +2, -2.. standard deviations from the mean on the sampling distrubution. The boxes correspond to the mean, +2 standard deviations from...

Suppose that a particular candidate for public office is in fact favored by 49% of all registered voters in the district. A polling organization will take a random sample of 750 voters and will use p̂, the sample proportion, to estimate p. What is the approximate probability that p̂ will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election? (Round your answer to four decimal places.)

Prior to a local election, you would like to estimate the percentage of voters that are in favor of a 4% increase in gasoline sales tax in order to generate enough revenue for street repair. You decide to take a random sample of 400 local voters to see if at least 60% of voters support this initiative. Use this information to answer question 1a to 1e. (Hint: recall that for a Bernoulli random variable, the standard deviation is p(1 –...

(1 point) A poll of n voters is to be taken in an attempt to predict the outcome of a by- election in a certain riding. Specifically, you are interested in the proportion of voters that will vote for a certain candidate, Candidate A. n = 410 voters have been randomly chosen, each has indicated what candidate they will vote for. You are to count the number, out of 410, who say they will vote for Candidate A. This count...
