Answer:
here distribution is Binomial Distribution
n = 1000, p = 0.0001
The population mean is computed as:
=n * p
=1000 * 0.0001
=0.1
Mean = 0.1
formula for population variance is
=n * p *(1−p)
=1000⋅0.0001⋅0.9999
=0.1
population variance= 0.1

If 1000 bits are transmitted, determine the following Round your answers to four decimal places (e.g. 98.7654) (a) P(X = 1) (b) P(X 2 1) (c) P(X s 2) (d) mean and variance of X. (d) Mean = variance =
9.1.10 Your answer is partially correct. Try again. A manufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed, with standard deviation 0.70 volt, and the manufacturer wishes to test Ho : u = 5 volts against H1 : u + 5 volts, using n = 5 units. Round your answers to four decimal places (e.g. 98.7654). (a) The acceptance region is 4.83 < Ñ < 5.10....

Please answer b Your answer is partially correct. Try again. Suppose that P (AIB) = 0.44 and P (B) = 0.51. Determine the following. Round your answers to four decimal places (e.g. 98.7654). ye) PAnB) T0.2244 (b) P(A'nB
Your answer is partially correct. Try again. A photoconductor film is manufactured at a nominal thickness of 25 mils. The product engineer wishes to increase the mean speed of the film, and believes that this can be achieved by reducing the thickness of the film to 20 mils. Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square inch) is measured. For the 25-mil film, the sample data result...
Your answer is partially correct. Try again. Supercavitation is a propulsion technology for undersea vehicles that can greatly increase their speed. It occurs above approximately 50 water to dissociate into water vapor forming a gas bubble behind the vehicle. When the gas bubble completely encloses the vehicle, supercavitation is said to occur. Eight (n = 8) tests were conducted on a scale model of an undersea vehicle in a towing basin with the average observed speed = 102.2 meters per...
Chapter 10 Section 1 Additional Problem 1 Your answer is partially correct. Try again. Consider the hypothesis test Hi : Mi = u2 against Hp : Mi <H2 with known variances (j = 10 and 62 = 6. Suppose that sample sizes nj = 11 and 12 = 14 and that j = 14.3 and 12 = 19.6. Use a = 0.05. (a) Test the hypothesis and find the P-value. (b) What is the power of the test in part...

Reserve Problems Chapter 10 Section 1 Problem 3 Your answer is partially correct. Try again. The time delay is measured for a city street. Variability in this value is estimated as o = 0.3 (for time in minutes) by experience. Traffic signs and lights were recently altered to facilitate traffic and reduce delays. Delay times in minutes for a random car sample before and after the rearrangement are shown below. Before 7.2 7.1 7.1 7.0 7.3 7.1 6.7 6.8 7.1...
