Problem H-802. This is based on Chapter 5.4; the tea'tbook problems in Oh. 5.4 are too advanced. (a) Compute the sample mean, sample variance, and sample standard deviation of these values: 54, 69, 76, 80, 84, 57 (b) 3:1, . . . ,3150 have sum 200 and the sum of their squares is 3000. Compute the sample mean, sample variance, and sample standard deviation of those numbers. ((3) A survey question asks people about their annual income range. 23 people respond $0$10K, 7 respond $10K$20K, 6 respond $20K$30K, and 4 respond $30K$40K. Estimate the sam- ple mean, sample variance, and sample standard deviation of the annual income. Include units for each of these
