Answer:
D. 5
Step-by-step explanation:
The statement is False.
For this, it is enough to show a case in which the subtraction of two positive numbers is negative.
For this, we must choose two numbers.
Suppose we want to subtract the following numbers:
Number 1: 5
Number 2: 10
Subtracting both numbers we have:
We observe that the result is negative. Therefore, the given conclusion is false.

Counterexample:
Answer:
23
Step-by-step explanation:
3-(-3)+17
get rid of the parenthesis and negatives and make it into a positive.
3+3+17
add 3+3
6+17
add
=23
Answer:
a: 11.12%
b: about 2.5%
c: about 2.5%
Step-by-step explanation:
For this situation:
n = 1500
p = 0.35
q = 1 - p = 0.65
a: Find: P(p < 0.335)
See attached photo 1 for the solution
b. Find P(p > 0.37)
Since it says that σ = 0.01, and it's asking for the percent of the proportion larger than 0.37, they are asking for the percent of the proportion that is 2 standard deviations higher than the mean. Using the 68-95-99.7 rule, we have a total of 5% of data that is more than 2 standard deviations away, but that is on both sides of the mean. Divide that in half to get the total above 0.37. So there should be about 5%/2 = 2.5% of the proportions.
c: Find P(p < 0.33)
0.33 is 2 standard deviations below the mean, so the percentage is 2.5% for similar reasons for part b
