The following sets of data represent the cost of living index for utilities and the cost of living index for transportation for 46 randomly chosen metropolitan areas in the United States.

utilities=c(90,84,85,106,83,101,89,125,105, 118,133,104,84,80,77,90,92,90, 106,95,110,112,105,93,119,99,109, 109,113,90,121,120,85,91,91,97, 95,115,99,86,88,106,80,108,90,87)

transportation=c(100,91,103,103,109,109,94,114,113, 120,130,117,109,107,104,104,113,101, 96,109,103,107,103,102,101,86,94, 88,100,104,119,116,104,121,108,86, 100,83,88,103,94,125,115,100,96,127)

Include your R commands and output for each part of the problem

1. Create a single table summarizing the mean, median, mode, standard deviation, variance and 5-number summary for each data set.
2. Create a boxplot for cost of living index for utilities.
3. Create a boxplot for the cost of living index for transportation.
4. Write a short paragraph comparing the two data sets and include lots of details.

you have been asked to study the mean yearly tuition at private four-year colleges and universities across the United States. You are interested in making some decisions concerning this population parameter. You select a random sample of 50 universities from this population. The mean tuition at these universities is found to equal $18,205. You still have reason to believe that the population standard deviation of the tuition amounts is known to equal $9,000. At both the 5% and 10% levels of significance, is the mean tuition at this population of universities less than $20,000? In your memo, if appropriate, comment upon the effect of the change in the significance level on your decision.

Lakonishok Equipment has an investment opportunity in Europe. The project costs €12 million and is expected to produce cash flows of €2.7 million in year 1, €3.1 million in year 2, and €2.8 million in year 3. The current spot exchange rate is $1.3/€. The current risk-free rate in the United States is 5 percent, compared to that in Europe of 3.5 percent. The appropriate discount rate for the project is estimated to be 18 percent, the U.S. cost of capital for the company. In addition, the subsidiary can be sold at the end of three years for an estimated €6.5 million. What is the NPV of the project?

In order to estimate the mean 30-year fixed mortgage rate for a home loan in the United States, a random sample of 24 recent loans is taken. The average calculated from this sample is 6.80%. It can be assumed that 30-year fixed mortgage rates are normally distributed with a population standard deviation of 0.5%. Compute 95% and 99% confidence intervals for the population mean 30-year fixed mortgage rate. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answers to 2 decimal places. Enter your answers as percentages, not decimals.)

1) According to the Centers for Disease Control and Prevention (CDC), the mean total cholesterol level for persons 20 years of age and older in the United States from 2007–2010 was 197 mg/dL. a. What is the probability that a randomly selected adult from the population will have a total cholesterol level of less than 183 mg/dL? Use a standard deviation of 35 mg/dL and assume that the cholesterol levels for the population are normally distributed. b. What is the probability that a randomly selected sample of 150 adults from the population will have a mean total cholesterol level of less than 183 mg/dL? Use a standard deviation of 35 mg/dL.

Constructing Confidence Intervals In Exercises 17 and 18, you are given the sample mean and the sample standard deviation. Assume the variable is normally distributed and use a normal distribution or a t-distribution to construct a 90% confidence interval for the population mean u. If convenient, use technology to construct the confidence intervals.
