Question

Suppose you are working with a data set that is normally distributed, with a mean of 200 and a standard deviation of 44. Determine the value of x from the following information.

(Round your answers and z values to 2 decimal places, e.g. 1.25.)

(a) 60% of the values are greater than x. enter an appropriate value rounded to 2 decimal places

(b) x is less than 17% of the values. enter an appropriate value rounded to 2 decimal places

(c) 23% of the values are less than x. enter an appropriate value rounded to 2 decimal places

(d) x is greater than 60% of the values. enter an appropriate value rounded to 2 decimal places

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.
