Answer: False.
Step-by-step explanation:
For any random variable x,
Formula to calculate the z-score :
, where = Mean
= Standard deviation
Let x be the data point has a corresponding z-score of -1.5.
Then , we have
i.e. x is one and a half standard deviations below the mean value.
( one and a half = )
Therefore , the given statement is false.
Using proportions, it is found that they must win 19 of their next 30 games.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount, and the measures are related using a rule of three.
We want a win-to-loss proportion of 2:1, which is equivalent to a win-to-total proportion of 2:3. We have that:
Hence:
3(5 + x) = 72
15 + 3x = 72
3x = 57
x = 19.
The Rangers must win 19 of their next 30 games.
