Establish an approximate design to MTBF required for a system that will result in an approximate minimum total cost over a five year period if the system is to be operated 7500 hours per year, where
Total Cost (for 5 years) = Acquisition cost + Spare cost + Downtime cost
System acquisition cost is related to MTBF, θ, as follows:
CA(θ) = θe0.050
The average cost of downtime associated with failure is $9,000 and the average cost of a spare item is $2,000
What is the appropriate set of hypotheses to test such that a possible outcome of the test would indicate;
LINEAR PROGRAMMING MODELS
The conservative degrees of freedom for the t distribution are and The standard error, conservative degrees of freedom
Suppose among 312 large city residents sampled, 65 refused to cooperate. What is the margin of error at the 95% confidence level.
Solve the mean and standard deviation equations
Compute the value of the test statistic (to 2 decimals).
Your statistics instructor wants you to determine a confidence interval estimate for the mean test score for the next exam.
Would you expect the mean absolute percentage error to be more than or less than 0.25? Describe.
each person received was determined by randomization. For each person who was sent one of the surveys, the researcher recorded whether or not a completed survey was returned.
If the estimate is to be within 8 mpg of the true mean with 98% confidence and the estimated standard deviation is 22 mph, how large a sample size must be taken?
Compute and interpret each of the statistics in parts(a) through (f) Mean and Median.
Which of the following assumptions for inference about a proportion using a confidence interval are violated,
