The weight of an organ in adult males has a bell-shaped distribution with a mean of 330 grams and a standard deviation of 20 grams. Use the empirical rule to determine the following. (a) About 95% of organs will be between what weights? (b) What percentage of organs weighs between 310 grams and 350 grams? (c) What percentage of organs weighs less than 310 grams or more than 350 grams? (d) What percentage of organs weighs between 290 grams and 390 grams? (a) 290 and 370 grams (Use ascending order.) (b) 68 % (Type an integer or a decimal.) (c) 32 % (Type an integer or a decimal.) (d) |% (Type an integer or decimal rounded to two decimal places as needed.)
