The following TI-84 Plus display presents some population parameters. 1-Var-Stats x =158 E x=2680 E x =359,620 Sx=6.066300355 OX=6 I n=20 (a) Assume the population is bell-shaped. Approximately what percentage of the population values are between 140 and 176? (b) Assume the population is bell-shaped. Between what two values will approximately 68% of the population be? (c) If we do not assume that the population is bell-shaped, at least what percentage of the population will be between 140 and 176? Part 1 of 3 (a) Assume the population is bell-shaped.
