#5. A pаckаge delivery service prоvided the fоllоwing informаtion about the weights (rounded to nearest ounce) of 60 packages chosen at random. Mean Weight Median Weight Standard Deviation Minimum Weight Lower Quartile Upper Quartile Maximum Weight 32.35 26.5 16.63 8 19.5 45.5 64 Complete each statement with an integer or exact decimal to form a true statement. Do not round or approximate your response. a) 50% of the package weights are between 8 and [median] ounces. b) [percent]% of the package weights are between 19.5 and 45.5 ounces. c) 15 packages weighed between [quartile] and 26.5 ounces. d) 75% of the packages were at least [quartile1] ounces. e) The range of the package weights is [range] ounces. f) The interquartile range of the package weights is [iqr] ounces. g) The 75th percentile of the package weights is [p75]. h) The percentile rank of 19.5 is [pr]. i) The number of packages in the sample weighing between 8 and 26.5 ounces is equal to the number of packages withing between 19.5 and [q3] ounces. j) Create a boxplot on your own paper.
