Answer....

A collector of sports cards has 600 sports and seeks to determine their total value ( which is assumed to be the sum of individual card values). The cards are grouped by sport. They are 300 baseball card, 180 basketball cards, and 120 football cards. The collector draws a stratified random sample of size 25 baseball, 25 basketball and 25 football cards and observes the following sample data Sample Sample Stratum Sample size standard mean of deviation of cards value cards value Baseball 25 15 9 Basketball 25 19 17 Football 25 View the sample above as a pilot survey and use the information in it to design a survey to meet the following collectors goal. The collectors seeks to estimate the total value of the collection with a bound on the error of estimation $ 300, the collector want to use as small a total sample size as possible. How large a stratified random sample should the collector take? Select one: a. 433 b. 343 C. 334 d. 400A collector of sports cards has 600 sports and seeks to determine their total value ( which is assumed to be the sum of individual card values).
