True or False Questions.
Statistics' students of a class of Lyceum want to calculate the average number of chocolate pieces in a standard package of biscuits SANTAS. They choose a random sample of biscuits, measure chocolate pieces in each cookie and calculate the 95% confidence interval for the average of chocolate pieces per cookie (18.6 to 21.3).
Issues 1-4 are four different interpretations of the results. Note which of these is right and what not.
1)We are 95% sure that each cookie of this brand contains about 18.6 to 21.3 pieces of chocolate. (T/F)
2) We estimate that 95% of the cookies contain 18.6 to 21.3 pieces of chocolate. (T/F)
3) We suppose that 95% of the average of all possible samples of this population will range from 18.6 to 21.3 parts of chocolate. (T/F)
4) We are 95% confident that the confidence interval [18.6 to 21.3] contains the actual average chocolate chips per cookie. (T/F)
