Answer:
2.5% of IQ scores are no more than 65
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 95
Standard deviation = 15
Using the empirical rule, what percentage of IQ scores are no more than 65?
65 = 95 - 2*15
So 65 is two standard deviations below the mean.
By the Empirical Rule, 95% of the measures are within 2 standard deviation of the mean. Of those 5% which are not, 2.5% are more than 2 standard deviations above the mean and 2.5% are more than 2 standard deviations below the mean.
So 2.5% of IQ scores are no more than 65
If you live in Canada, then you live in Toronto.
To write a converse of a conditional statement, you have to exchange hypothesis and conclusion.
In your case : let "you live in Toronto" be x and "<span>you live in Canada" be y,
where hypothesis is x and conclusion is y.
so a short scheme of your sentence will be :" If x, then y" , but its converse will be viceversa : " if y, then x" . And this thing is applied for all cases.
