The testing times for a group of college students were normally distributed with a mean of u = 31 minutes and a standard deviation of o = 4.8 minutes. The bell curve below represents the distribution for testing times. The scale on the horizontal axis is equal to the standard deviation. Fill in the indicated boxes. µ = 31 o = 4.8 H-30 u-20 u-o μ+20 μ+3σ Used the Empirical Rule to complete the following statements: 68% of testing times were between minutes and minutes. 95% of testing times were between minutes and minutes. 99.7% of testing times were between minutes and minutes. 50% of testing times were below minutes.

Question

Transcribed Image Text:The testing times for a group of college students were normally distributed with a mean of u :
31 minutes
and a standard deviation of o = 4.8 minutes.
The bell curve below represents the distribution for testing times. The scale on the horizontal axis is equal
to the standard deviation.
Fill in the indicated boxes.
H = 31
4.8
O =
H-30 u-20 u - o
μ+ 20 μ+3σ
Used the Empirical Rule to complete the following statements:
68% of testing times were between
minutes and
minutes.
95% of testing times were between
minutes and
utes.
99.7% of testing times were between
minutes and
minutes.
50% of testing times were below
minutes.
