I believe it is a 62.5 percent chance.
Answer:
99.7% of IQ scores are between 46 and 148.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 97, standard deviation of 17.
What percentage of IQ scores are between 46 and 148?
97 - 3*17 = 46
97 + 3*17 = 148
Within 3 standard deviations of the mean, so:
99.7% of IQ scores are between 46 and 148.
Use a calculator to evaluate the left and right side separately.
4/3 = 24/30
1.333 = 0.8
The equation is false.
----------------------------------
Alternatively, you can cross multiply like so
4/3 = 24/30
4*30 = 3*24
120 = 72
Since that equation is false, it means that the original equation 4/3 = 24/30 is false.
