A major cab company in Chicago has computed its mean fare from O'Hare Airport to the Drake Hotel to be

$

28.99

, with a standard deviation of

$

3.79

. Based on this information, complete the following statements about the distribution of the company's fares from O'Hare Airport to the Drake Hotel.

(a) According to Chebyshev's theorem, at least ?56%75%84%89% of the fares lie between 21.41 dollars and 36.57 dollars.

(b) According to Chebyshev's theorem, at least ?56%75%84%89% of the fares lie between 19.515 dollars and 38.465 dollars.

(c) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately ?68%75%95%99.7% of the fares lie between 21.41 dollars and 36.57 dollars.

(d) Suppose that the distribution is bell-shaped. According to the empirical rule, approximately 99.7% of the fares lie between

1, 33% of consumers read the ingredients listed on a product's label. For a sample of 265 consumers, what is the probability that between 80 and 103 of them read the ingredients listed on a product's label?

2.

The hotel room rate in New York City is normally distributed with a mean of $294 per night. Assume that the standard deviation is unknown.

If 23% of the New York City hotel room rates are more than $328 per night, what is the variance? (Remember the label.)

3.

The Economic Policy Institute reports that the average entry-level wage for male college graduates is $22.23 per hour and for female college graduates is $18.97 per hour. The standard deviation for male graduates is $3.94 and for female graduates is $3.02. Assume wages are normally distributed.

If 30 female graduates are chosen, find the probability the sample average entry-level wage is at least $19.85

4. Julie visits the local park 90 times, and sees her favorite pigeon 38 times. Let p be the probability that Julie sees the pigeon on any given visit, and assume that whether Julie sees the pigeon on some visit is independent of whether she sees the pigeon on any other visit.

(a) Construct a 90% two-sided confidence interval for p.

(b) Julie believes that there is a 50% chance that she sees the pigeon when she visits the park. Is your interval in part (a) consistent with that belief? Explain your answer.

(c) Test Julie’s claim from part (b) with a hypothesis test. Use a significance level of α = 0.05. Perform the test by comparing a test statistic to a critical value found in the tables in the back of your textbook.

(d) Perform the test in part (c) using a p-value.

Explain the general concept behind rotary aircraft structure and construction methods.
And describe the airworthiness requirements applicable to the design and construction of a typical rotary aircraft fuselage and system such as phlone, fule storage and symmetry

How did modern construction learn from ancient constructions, building materials and technologies? How could the oldest building materials be applied to today’s construction? Or could it be modified to fit our needs?

1. UVW began construction of a new office building on March 1, Y1. On the day construction began, UVW borrowed $240,000 at 7% and immediately spent it on the project. An additional payment of $60,000 was also made on the day construction began. Additional expenditures of $75,000 were made on May 1 and August 31. Construction was complete and the building was placed in service on December 31, Y1. In addition to the $240,000 borrowed to finance the project, UVW also has $2,000,000 of other debt at 5% outstanding for the entire year.

   What is the balance in the building account on the December 31, Y1 balance sheet?

In a study to estimate the proportion of residents in a certain city and its suburbs who favor the construction of a nuclear power plant, it is found that 210 of 300 urban residents favor the construction while only 180 of 200 suburban residents are in favor.

(a) Is there a significant difference between the proportion of urban and suburban residents who favor construction of the nuclear power plant? α=0.05.

(b) Construct a 95% confidence interval for the difference of favor proportions between urban residents and suburban residents.

(c) By using the confidence interval from (b) test if there is a significant difference between the proportion of urban and suburban residents who favor construction of the nuclear power plant. (You need to explain how you make the conclusion)
