Question

Use a z-table such as https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf to answer the following question:

This question again refers to the study on blood pressure. What blood pressure value represents the 90th percentile? That is, what is the blood pressure value that would have 90% of the population beneath that value? The data is normally distributed with a mean of 120.1 mmHg and a standard deviation of 15.1 mmHg? Express your answer rounded off to 1 decimal place

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.
