**Text:**
*For males in a certain town, the systolic blood pressure is normally distributed with a mean of 120 and a standard deviation of 7. If 228 males from the town are randomly selected to participate in a study, how many of them would be expected to have a systolic blood pressure less than 136, to the nearest whole number?*

**Instructions:**
Use the normal distribution parameters given (mean = 120, standard deviation = 7) to calculate the probability that a randomly selected male has a systolic blood pressure less than 136. Then, multiply this probability by the sample size (228) to find the expected number of males with a systolic blood pressure less than 136.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
