Question

the measurement of the height of 600 students of a college is normally distributed with a mean of 175 centimeters and a standard deviation of 5 centimeters.
what percent of students are taller than 175 cm?
a. 34
b. 50
c. 68
d. 84

Answer 1

With any distribution, 50% of the data values will lie below the mean and 50% of the values will lie above the mean

Since the mean is 175 cm and we want to know "what percent of students are taller than 175 cm", this means that the answer is 50%

Answer 2

basically half of the students are taller than the mean height (which is the midpoint of the distribution)

Answer 3

thank you!!
