The mean lifetime of electric light bulbs produced by a company has in the past been 1120 hours with a standard deviation of 125 hours. A sample of 20 bulbs revealed a standard deviation in the lifetimes of 150 hours. Would you conclude that this is unusual? Explain.
Basic concepts. For each of the following, answer the question and give a short explanation of your reasoning.
Describe each of the following types of designs, explain its logic, and why the design does or does not address the selection threats of Trochim and Donnelly (2006):
What is the probability the average of the sample is more than $38000 and What is the standard deviation of the sample mean
Using What's Best! (or Solver) determine the least-cost shipping schedule, where each of three (3) hardware vendors provide up to two hundred (200) units and each of six (6) buyers demand one hundred (100) units.
Clinic evaluates that true population standard deviation is around $1,300. If confidence level is 95%, determine the required sample size in order to meet desired accuracy.
An investment counselor would like to meet with 14 of his clients on Wednesday, but he only has time for 10 appointments. How many different combinations of the clients could be considered for inclusion into his limited schedule for that day?
State the null and alternative hypotheses for the ANOVA (include definitions of parameters). What assumptions do we need to proceed with ANOVA?
The sample mean of the accounts is found to be y-bar = $94.22, and the sample variance is equal to $455.21. Estimate mu and place a bound on the error of estimation.
Define the standard error of the mean. What happens to the standard error as the sample size increases? Explain
How large should n be so that the standard deviation of is no more than 0.01 and sampling distribution
Determine the p-value; and at 93.7% confidence, test the above hypotheses.
Modify above problem (Problem 8th) so that each hardware vendor now demands seventy-five (75) units. Any units available from the vendors that are not shipped cost nothing.)
