(Do not round intermediate calculations and enter your answer as o percent rounded to 2 decimal places, e.g., 32.16.) a-2. What is the variance? (Do not round intermediate calculations and round your answer to 5 decimal places, e.g., .16161.) a-3. What is the standard deviation? (Do not round intermediate calculations and enter your onswer os o percent rounded to 2 decimal places, e.g., 32.16.) b.
