1. (10 Points) We have a sample as follows. 12 12 16 16 20 22 30 28 26 26 22 28 32 32 30 30 28 26 (1) Draw the histogram or frequency table for the sample. (2) Compute the median, mean, and variance of the sample. (3) What is the mode or shape of the sample? (4) Compute the percentage of region within at most two standard variance from the mean. (5) What is sample space for the sample? (6) Compute the probability of the event that outcome is no more than 28. (7) Compute the probability of the event that outcome can be divided by 4.
