IQ Scores have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. What percentage of IQ scores are between 70 and 130?
<span>Solution: </span>130 – 100 = 30 which is 2(15). Thus, 130 is 2 standard deviations to the right of the mean. 100 – 70 = 30 which is 2(15). Thus, 70 is 2 standard deviations to the left of the mean. Since 70 to 130 is within 2 standard deviations of the mean, we know that <span>about 95% of the IQ scores would be between 70 and 130.</span>

Plural Executive was created on 1876 constitution where there is a fragmented system of authority through which most statewide executive office holder are elected independently of governor.
However, one problem of plural executive is the potential conflict between governor & executive officials so when conflict emerges between state officials of the plural executive, the governor is most likely to become involved.
I would say the answer would probably be initiate worker training program’s
Answer:
D. $29.40
Explanation:
Calculation for the mean cost per customer for the performance
Using this formula
Mean cost per customer=[(Number of tickets purchased*Relative frequency)]*Performance cost
Let plug in the formula
Mean cost per customer=[(1*0.20)+(2*0.45)+(3*0.10)+(4*0.20)+(5*0.05)]*$12
Mean cost per customer=(0.2+0.9+0.3+0.8+0.25)*$12
Mean cost per customer=2.45*$12
Mean cost per customer=$29.40
Therefore the mean cost per customer for the performance will be $29.40
