Given: error: 6 months, standard deviation = 5 years is 60 months
Step 1: find the minimal sample size ‘n’ for 95% confidence interval
1-0.95= 0.05
0.05/2= 0.025
Step 2:
1-0.025= 0.975

Answer:
-4.25
Step-by-step explanation:
The given number is 4.25 and we have to find the opposite of this number.
Opposite of a number is also known as additive inverse and it is defined as "if the sum of two numbers is zero then two numbers are opposite or additive inverse of each other"
For example, if x is a number then its opposite is -x.
and hence, x + (-x) = 0
Using this fact, we can conclude that the opposite of 4.25 is -4.25 because
4.25 + (-4.25)
= 4.25 - 4.25
=0
