Q1) To evaluate the true mean weight of packages received by parcel service, 39 packages are arbitrarily chosen and weighed. Sample has mean weight of 15.3 pounds and standard deviation of 1.9 pounds. Construct a 95% confidence interval estimate for true mean weight of all packages received by parcel service.
Q2) Sociologist develops the test to measure attitudes about public transportation, and 27 arbitrarily chosen subjects are given test. Their mean score is 76.2 and their standard deviation is 21.4. Create the 90% confidence interval for mean score of all such subjects. You may suppose scores are usually distributed.
To select a _________ sample, an intact group of subjects that represent the population is selected.
The paired data below consist of the test scores of 6 randomly selected students and the number of hours they studied for the test.
The weight of the first orange minus the weight of the second orange) is a random variable with standard deviation and individual outcomes are uncertain but happen in a predictable manner through time.
Multiple comparison procedures are going to be done using the Bonferroni method with α = 0.10. The value of t** is 2.2426. The smallest minimum significant difference (MSD) for finding a difference between groups is computed as 17.68. The correct ..
Compare your best difference to the result from an ordinary two-sample t-test between these groups. Comment the difference.
