Suppose that a sample of 50 boxes of chocolates are weighed and the sample mean weight is 495.9321. The output below, shows the corresponding tolerance interval. Which one of the following interpretations of this tolerance interval is correct? library(tolerance) normtol.int(x=choc.dat, alpha = 0.05, P = 0.99, side = 2) alpha P x.bar 2-sided.lower 2-sided.upper 1 0.05 0.99 495.9321 429.775 562.0893 (a) We are 95% confident that the true average weight of all boxes of chocolates in the population of interest is likely to be between 429.775 and 562.0893. (b) We are 99% confident that the true average weight of all boxes of chocolates in the population of interest is likely to be between 429.775 and 562.0893. (c) We are 95% confident that the true weight of 99% of the boxes of chocolates is likely to be between 429.775 and 562.0893. (d) We are 99% confident that the true weight of 95% of the boxes of chocolates is likely to be between 429.775 and 562.0893.
