For a population with mean (μ) = 100 and standard deviation (σ) = 20, the X value corresponding to z = 1.50 is 130.
<h3>What is a z-score?</h3>
A z-score is also referred to as a standard score and it's a measure of the distance between a raw score and the mean, when standard deviation units are used.
<h3>How to determine the value of x?</h3>
In Statistics, the standardized z-score is giving by this formula:

Making x the subject of formula, we have:
x = Zσ + μ
Substituting the given parameters into the formula, we have;
x = 1.50(20) + 100
x = 30 + 100
x = 130.

Answer:
4.8 Liters
Step-by-step explanation:
Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy
Step 1
1 person = 200ml of ice cream
24 persons = x
Cross Multiply
x = 24 × 200ml of ice cream
x = 4800 ml of ice cream
Step 2
How many liters of ice cream should she buy
We convert from Milliliters to Liters
1 milliliters= 0.001 liters
4800 millilitres = x
Cross Multiply
= 4800 × 0.001 liters
= 4.8 Liters
Therefore, she should buy 4.8 Liters of ice cream
