In a study to investigate the effect of the color paper (blue, green, orange) on response rates for questionnaires distributed by the "windshield method" in supermarket parking lots, four supermarket parking lots were chosen in a metropolitan area and 10 questionnaires of each color were assigned at random to cars in the parking lots.
a. Is this study experimental, observational, or mixed? Why?
b. Identify all factors, factor levels, and factor-level combinations.
c. What type of study design is being implemented here? Completely randomized, randomized complete block, nested designs, repeated measures? explain
d. What is the basic unit of study?
A researcher obtains t = 4.00 and MD = 9 for a repeated-measures study. If the researcher measures effect size using the percentage of variance accounted for, what value will be obtained for r2?
A retail grocer has decided to market organic "health foods" and will purchase a new line of products from each of two suppliers. Unknown to the grocer
The population of lengths of aluminium-coated steel sheets is normally distributed with a mean of 30.05 inches and a standard deviation of 0.2 inches.
Explain why those rates may be more meaningful as a measure of change across time than the actual numbers of those events.
What is the characteristic function of N? What is the mean and variance of N? What is the pmf of N? What is the probability that N is an even number?
What is the probability that exactly 3 tomatoes in a randomly selected tray of 20 tomatoes will be too ripe. In each tray of 20 tomatoes, how many would be expected to be too ripe?
Estimating the sample standard deviation using normal score - Find the sample standard deviation?
Average of $800 per month and a standard deviation of $50 per month. Find the probability that a randomly selected month had a personal call expense that falls below $650.
Find the expected frequency to test the claim that walking and low, moderate, and high blood pressure are not related. Round to the nearest tenth if necessary.
An independent-measures research study was used to compare two treatment conditions with n = 4 participants in each treatment. The first treatment had a mean of M = 58 with a variance of s^2 = 28, and the second treatment had M = 52 with s^2 = 36.
