Suppose we have N = 6 values from a population. These values are 4, 8, 0, 10, 14 and 6. Let μ and σ denote the population mean and population standard deviation of these six values, respectively. (a) What are the values of μ and σ, respectively? μ = 4.8580; σ = 7 μ = 7; σ = 4.8580 μ = 7; σ = 4.4347 μ = 7; σ = 19.6667 μ = 7; σ = 23.6 (b) What percentage...

I have an 8 by 8 array that has values ranging from 1-64. I am wanting to display the array evenly but due to some digits being single and others double, it displays lopsided. What would be the best way to get everything in the array to display in a nice even square?

Suppose, for a random sample selected from a normal population, we have the values of the...

Suppose, for a random sample selected from a normal population, we have the values of the sample mean x ̄ = 67.95 and the standard deviation s = 9. a. Construct a 95% confidence interval for population mean μ assuming the sample size n = 16. b. Construct a 90% confidence interval for population mean μ assuming n = 16. c. Obtain the width of the confidence intervals calculated in a and b. Is the width of 90% confidence interval...

Suppose we see the following prices for zero coupon bonds with maturities ranging from one to six years: Maturity in Years Bond Price 1 $98.04 2 $95.18 3 $92.18 4 $89.28 5 $86.52 6 $83.90 Note: Each bond has a face value of $100 a) What do you expect the five-year spot rate to be one year from now? Please report the annual rate. b) What is the yield-to-maturity of a six-year coupon bond that has a face value of...

17#13 Suppose we roll a fair six-sided die and sum the values obtained on each roll, stopping once our sum exceeds 289. Approximate the probability that at least 76 rolls are needed to get this sum.

Suppose we have a face recognition system with an accuracy of 90%. Suppose it is deployed in a security system that observes 40 people. Compute the following probabilities ( You should write down the expression mathematically, and an R expression that returns the answer ): (a) It fails for exactly 6 people. (b) It fails for at most 2 people. (c) It fails for at least 8 people

Suppose we have a box model representing a die: [1,2,3,4,5,6] with a mean of μ=3.5 and a standard deviation of σ=1.708. If we do 88 rolls of the die what will our expected value and standard error be for our sampling sum, respectively? Suppose we have the following box representing our population [0, 1, 1, 2, 3, 5] with μ=2.0 and σ=1.79. If we sample or draw from this population 35 times, what is the probability that the sum exceeds...

Suppose we have a mass of 12 pounds on a spring which stretches by 1/2 foot from the weight. If we have a forcing function g(t) = cos(8t), no damping, and y(0) = y ′ (0) = 0, describe the motion of the system. Our mass is 12/32 = 3/8, and k = mg/L = 12/(1/2) = 24. USE DETERMINANT METHOD.
