The mean time to expose a single panel in a circuit-board plant is two minutes with a standard deviation of 1.5 minutes.
a. What is the natural coefficient of variation?b. If the times remain independent, what will be the mean and variance of a job of 60 panels? What will be the coef cient of variation of the job of 60?c. Now suppose times to failure on the expose machine are exponentially distributed with a mean of 60 hours and the repair time is also exponentially distributed with a mean of two hours. What are the effective mean and CV of the process time for a job of 60 panels?
Which measure of central tendency would you use to summarize the data below? Which inferential test would you use to determine if there is a difference in rainfall between the sample 2 and 3?
What is the probability that in your random sample of 50 students, between one thirds and two thirds favor the new policy?
In order to test to see if there is any significant difference in the mean number of units produced per week by each of three production methods, the following data were collected:
Federal administration stated that unemployment level in US is 8.6% (population proportion = 0.086). A hypothesis test is to be performed to decide whether unemployment level in NY State differs from national level.
State the values of the coefficient of correlation and coefficient of determination correct to three decimal places
Let x be N(µ,σ2 ) and consider the transformation x=log(y) or equivalently y=exp(x). Find the mean and the variance of y by first determining E(exp(x)) and E[(exp(x)^2 ], by using the moment generating function of x.
Determining the strength of a correlation is very important to determine how well one variable can predict another. To determine the strength of a correlation, we have to calculate the correlation coefficient, r.
Describe the standard normal distribution. Explain why it can be used to find probabilities for all normal distributions.
The margin of error for a 95% confidence interval estimate for the proportion of all students with cell phones is
Assume that ages at onset of this disease are normally distributed for each gender, do not assume the population variances are equal. What are the appropriate null and alternative hypotheses?
The probability that a randomly selected elementary or secondary school teacher from a city is female is 0.68, holds a second job is 0.38, and is female and holds a second job is 0.29.
After 1,000-trial simulation, examine statistical information generated and compare output of simulation with your findings in Problem .Briefly describe the significant similarities and differences.
