Hello, please help me solve this.

The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 261.7 and a standard deviation of 67.4. (All units are 1000 cells/jL.) Using the empirical rule, find each approximate percentage below. a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or between 194.3 and 329.1? b. What is the approximate percentage of women with platelet counts between 126.9 and 396.5? a. Approximately % of women in this group have platelet counts within 1 standard deviation of the mean, or between 194.3 and 329.1. (Type an integer or a decimal. Do not round.) b. Approximately |% of women in this group have platelet counts between 126.9 and 396.5. (Type an integer or a decimal. Do not round.)
