Answer:
The correct statement would be: The positive number is 1/2 unit less than the opposite of the negative number.
Step-by-step explanation:
All stamemts are true except for the last one:
<em>The positive number is 1/2 unit more than the negative number.</em>
We can see in the plot that 1.5 is above zero and -2 is below zero.
So, -2<1.5
The opposite number of -2 is 2 and we can see that opposite number is 1/2 greater than 1.5. So, -2<1.5<2

Using the normal distribution, it is found that the probability is 0.16.
<h3>Normal Probability Distribution</h3>In a normal distribution with mean and standard deviation
, the z-score of a measure X is given by:
In this problem, the mean and the standard deviation are given by, respectively, .
The proportion of students between 45 and 67 inches is the p-value of Z when <u>X = 67 subtracted by the p-value of Z when X = 45</u>, hence:
X = 67:
Z = -1
Z = -1 has a p-value of 0.16.
X = 45:
Z = -8.3
Z = -8.3 has a p-value of 0.
0.16 - 0 = 0.16
The probability is 0.16.
