To determine the minimum sample size
Minimum Sample Size for Camcorders
July 9, 2019Power Analysis and type of quantitative test
July 9, 2019A researcher conducted a study of the access speed of 45 hard drives and concluded that the maximum error of estimate was .28. If he were to conduct a second study to reduce the maximum error of estimate to 7, about how many hard drives should he include in his sample?
a. 720
b. 180
c. 45
d. 90
Maximum error of estimate = Upper limit of the error margin = SD/sqrt N
First, …
Sample size determination for a given error margin. Neat and step-by-step solution is provided.
