Use descriptive statistics to summarize each of the three variables for the 40 Gulf View condos. Describe the distribution of each variable. Repeat for the 18 No Gulf View Condos. (This includes the five-number summary, the mean, standard deviation, and a histogram of each variable). Gulf View condos are denoted by “1” in the Gulf View column, whereas No Gulf View condos are denoted by “0”. Prices are in thousands of dollars.

Create a box plot for each of the three variables, with Gulf View and No Gulf View condos represented by a separate box. Compare the distributions between the two groups along with the statistics in question (1). Discuss any specific statistical results that would help a real estate agent understand the condominium market. ( Gulf View condos are denoted by “1” in the Gulf View column, whereas No Gulf View condos are denoted by “0”. Prices are in thousands of dollars.)

You would like to buy a house that costs$ 350 comma 000$350,000.You have$ 50 comma 000$50,000

in cash that you can put down on the​ house, but you need to borrow the rest of the purchase price. The bank is offering you a​ 30-year mortgage that requires annual payments and has an interest rate of

7 %7%

per year. You can afford to pay only

$ 23 comma 210$23,210

per year. The bank agrees to allow you to pay this amount each​ year, yet still borrow

$ 300 comma 000$300,000.

At the end of the mortgage​ (in 30​ years), you must make a balloon​ payment; that​ is, you must repay the remaining balance on the mortgage. How much will be this balloon​ payment?

​Hint: The balloon payment will be in addition to the 30th payment.

2.

You are thinking of building a new machine that will save you

$ 5 comma 000$5,000

in the first year. The machine will then begin to wear out so that the savings decline at a rate of

3 %3%

per year forever. What is the present value of the savings if the interest rate is

8 %8%

per​ year?

The present value of the savings is ​$nothing. ​(Round to the nearest​ dollar.)

25)Sosin Inc. manufactures hydrogen engines. Recently 350 new orders placed by customers requesting credit. The variable cost is $16,000 per unit, and the credit price is $18,400 each. Credit is extended for one period, and based on historical experience, payments for 15% of the orders are never collected. The required return is 3% per period. Suppose that customers who don’t default become repeat customers and they never default. Calculate the NPV?

Suppose we have 30-day follow-up data on 350 ischemic stroke patients and want to investigate whether the risk of recurrent stroke and/or death (RD) depends on the type of stroke. You classify patients according to initial stroke type-having a cerebral embolism (CE = 1) or not (CE = 0).

c) Is the risk of RD the same for CE and non-CE patients? Estimate the relative risk of RD.

1. The equilibrium constant, K_c, for the following reaction is 9.52×10^-2at 350 K.

CH₄(g) + CCl₄(g) = 2 CH₂Cl₂(g)

Calculate the equilibrium concentrations of reactants and product when 0.300 moles of CH₄and 0.300 moles of CCl₄are introduced into a 1.00 L vessel at 350 K.

A survey found that the American family generates an average of 17.2 pounds of glass garbage each year. Assume population is normally distributed with standard deviation of 2.5 pounds. Find the probability that the mean of a sample of 55 families will generate between 17 and 18 pounds.
