Suppose that you take 800 simple random samples from a population and that, for each sample, you obtain a 99% confidence interval for an unknown parameter. Approximately how many of the confidence intervals will contain the value of the unknown parameter? Round to a whole number.
Homework Answers
Answer
Given that
sample size n = 800
and confidence level = 0.99
so, expected number of confidence intervals will contain the value of the unknown parameter is given as
E[x] = n*(confidence level)
= 800*0.99
= 792 confidence intervals will contain the value of the unknown parameter

1. A simple random sample of 35 has a mean of 44.3 miles and a standard deviation of 2.0 miles. Which of the following is a 99% confidence interval estimate for the population mean? a. (43.637,44.963) b. (43.429 , 45.171) c. (43.378 , 45.222) d. (43.613 , 44.987) We will take 200 simple random samples, each of size 50, from the given population and calculate the 90% confidence interval for μ for each. Approximately how many 200 intervals will contain...

100 random samples were taken, and for each random sample we made a 95% confidence interval, about how many of those 100 confidence intervals would actually contain the parameter? Increasing the confidence level (more than one) a increase the width of a confidence interval b increase the probability that the parameter is in the confidence interval c increase the percentage of samples which will create a confidence interval that contains the parameter d Increase the margin of error A...

You collect a random sample of size n from a population and calculate a 98% confidence interval. Which of the following strategies produces a new confidence interval with a decreased margin of error? A.) Use a 99% Confidence level B.)Use a 95% confidence level C.)Decrease Sample Size D.)Use the same confidence level but compute the interval n time. Approximately 2% of these intervals will be larger. E.)Nothing can guarantee that you will obtain a larger margin of error. You can...

Simple random sampling uses a sample of size n from a population of size N to obtain data that can be used to make inferences about the characteristics of a population. Suppose that, from a population of 58 bank accounts, we want to take a random sample of four accounts in order to learn about the population. How many different random samples of four accounts are possible?
