Answer:
We want to construct a confidence interval at 99% of confidence, so then the significance level would be 
and the value of 
. And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.
And if we find the critical value in the normal standard distribution or excel and we got:
And we can use the following excel code:
"=NORM.INV(0.005,0,1)"
Step-by-step explanation:
For this case we have the following info given:

12!!!! Hope this helped and good encouragement
You can use quarts to convert
first do pints to quarts
then do quarts to gallons
Hello there!
Since we're looking for an equation to have a solution of x = -5, let's solve them from answer choice "A.)" to answer choice "D.)"
x + 10 = -5
x = -15
A.) is not correct.
Let's try B.)
-x^2 + 50 = 25
x^2 = -25
x = -5
Answer choice B.) is correct.
Let's continue looking for answer choices, just in case.
Let's look at answer choice C.)
2x = 10
x = 5
This answer is not correct.
Let's look at answer choice D.)
x < 0
This means x is less than 0, or a negative number.
This answer is not specifically correct.
Let's look at answer choice E.)
2x < 10
x < 5
This is less than 5, but does not specifically answer our chances.
Your answer is B.)
I hope this helps!
