Steam enters a partially open valve operating
$1.00

Steam enters a partially open valve operating at steady state as saturated liquid at 300 degrees F and exits at 60 lbf/in^2. Neglecting kinetic and potential energy effects and any stray heat transfer with the surroundings determine the temperature, in degrees F, and the quality of the steam exiting the valve.

Text:Water vapor at 5MPa, 320 degree C enters a turbine operating at steady state and expands to 0.1 bar^2. The mass flow rate is 2.52 kg/s, and the isentropic turbine efficiency is 92%. Stray heat transfer and kinetic and potential energy effects are negligible. Determine the power developed by the turbine, in kW.

A 25 Kw series generator has an efficiency of 85%
$1.00

A 25 Kw series generator has an efficiency of 85% when operating at rated load. If the stray-power loss is 20% of the full-load loss, calculate the efficiency of the generator when it is delivering a load of 15Kw, assuming that the stray-power loss is substantially constant and the other losses vary as the square of the load.

Question
$5.00

Americans have become increasingly concerned about the rising cost of Medicare. In 1990, the average annual Medicare spending per enrollee was $3267; in 2003, the average annual Medicare spending per enrollee was $6883 (Money, Fall 2003). Suppose you hired a consulting firm to take a sample of fifty 2003 Medicare enrollees to further investigate the nature of expenditures. Assume the population standard deviation for 2003 was $2,200.

A. Calculate the standard error of the mean amount of Medicare spending for a sample of fifty 2003 enrollees (to 2 decimals).

B. What is the probability the sample mean will be within +/- $300 of the population mean (to 4 decimals)?

C. What is the probability the sample mean will be greater than $7500 (to 4 decimals)?

If the consulting firm tells you the sample mean for the Medicare enrollees it interviewed was $7500, would you question whether the firm followed correct simple random sampling procedures?
– Select your answer -Yes, because the probability of attaining that sample mean is very highYes, because the probability of attaining that sample mean is very lowNo, because the probability of attaining that sample mean is very highNo, because the probability of attaining that sample mean is very lowItem 4

Question 2:

A market research firm conducts telephone surveys with a 38% historical response rate. What is the probability that in a new sample of 400 telephone numbers, at least 150 individuals will cooperate and respond to the questions? In other words, what is the probability that the sample proportion will be at least 150/400 = .375?

Calculate the probability to 4 decimals.

Question 3:

A random sample of the ages of 77 college students has a mean of 12. The population is known to be normal with a standard deviation, ?, of 5.

a. What is the standard error of the mean? (Round to 2 decimal places. Example: 3.87)

b. What is the margin of error, with 95% confidence? (Round to 2 decimal places. Example: 3.87)

Question 3:

You receive 100 yes responses on a survey of 436 people (n).

(Round your answers to two decimal places. Example: 1.51)

a. What is the point estimate of the proportion of the population (p) that would say yes?

b. Estimate the standard error of the population proportion.

c. Determine the 95% confidence interval.
