Based on data set 3 in appendix b, body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°f and a standard deviation of 0.62°f. using the empirical rule, what is the approximate percentage of healthy adults with body temperatures (a) between 97.58°f and 98.82

The empirical rule tells you 68% of the population is within 1 standard deviation of the mean. Your limits are 1 standard deviation from the mean, so your percentage is ...

... 68%

98.20 - 0.62 = 97.58 . . . 1 standard deviation below the mean

98.20 + 0.62 = 98.82 . . . 1 standard deviation above the mean

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
