Assume that blood pressure readings are normally distributed with a mean of 117 and a standard deviation of 8. If 100 people are randomly selected, find the probability that their mean blood pressure will be less than 119.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

Is it multiple choice
