Risk-free zero rate is 4% per annum with continuous compounding for all maturities and defaultsonly occur at times 0.25 years, 0.75 years, 1.25 years, and 1.75 years in a two-year credit default swap with semiannual payments. The probabilities of default are 0.8%, 1%, 1.2% and 1.5% in the first, second, third and forth six months of the CDS’s lifetime. The recovery rate is 60%. Calculate the CDS spread. Do not need in binary CDS

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally distributed, with a mean of 5.4 millimeters (mm) and a standard deviation of 0.8 mm. For a randomly found shard, find the following probabilities. (Round your answers to four decimal places.) (a) the thickness is less than 3.0 mm (b) the thickness is more than 7.0 mm (c) the thickness is between 3.0 mm and 7.0 mm

An experiment was conducted to compare the alcohol content of soy sauce on two different production lines. Production was monitored eight times a day in both production lines. Production line 1 has a sample standard deviation of 0.15 and Production line 2 has a sample standard deviation of 0.8. Assume both populations are normal.

State and conclude your hypothesis at the 0.05 level of significance if the both of production lines have the same variability?

The shape of a limacon can be defined parametrically as                                  

The shape of a limacon can be defined parametrically as

                                   r = r0 + cos θ,

                                   x = r cos θ,

                                   y = r sin θ.

When r0 = 1, this curve is called a cardioid. Use this definition to plot the shape of a limacon for r0 = 0.8, r0 = 1.0, and r0 = 1.2. Be sure to use enough points that the curve is closed and appears smooth (except for the cusp in the cardioid). Use a legend to identify which curve is which. This is python programming

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 280 engines and the mean pressure was 5.2 pounds/square inch (psi). Assume the population standard deviation is 0.8. If the valve was designed to produce a mean pressure of 5.3 psi, is there sufficient evidence at the 0.01 level that the valve performs below the specifications? Step 2 of 6 : Find the value of the test statistic. Round your answer to two decimal places.

Jachuck et al. (1982) report on an analysis of a certain drug designed to reduce hypertension (high blood pressure). Such hypotensive drugs are frequently effective but are also linked to side effects like irritability, a decline in energy, and a loss of sexual interest. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and relatives (typically spouses). Suppose that everyone agrees that the quality weight for hypertension is q = 0.8. That is, one year spent with mild hypertension is equivalent to 0.8 years of full health.

a. When asked to rate the treated patients as improved, worse, or unchanged, the doctors rated all 75 as “improved.” Meanwhile, the spouses rated 74 of the 75 patients “worse.” Why might spouses and doctors differ in their opinion about the effect of going on hypotensive therapy.

b. Explain why the drugs might be a dominated treatment and indicate what other treatment(s) might dominate it. c. Make a one-sentence argument for each of two viewpoints: • Doctors’ opinions should be used to determine how beneficial hypotensive drugs are for the purposes of CEA. • Spouses’ opinions should be used to determine how beneficial hypotensive drugs are for the purposes of CEA.
