Answer:
By the Central Limit Theorem, the average value for all of the sample means is 14.
Step-by-step explanation:
We use the central limit theorem to solve this question.
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sample means of size n can be approximated to a normal distribution with mean
and standard deviation, which is also called standard error
If the population mean is μ = 14, then what is the average value for all of the sample means?
By the Central Limit Theorem, the average value for all of the sample means is 14.
The number of cups of fruit salad that will be in each container is; 3³/₄ cups of fruit salad
<h3>How to divide fractions?</h3>We are given the table showing the amount of cups of each ingredient as attached.
From the table we see that;
Amount of cups of Pineapple = 2³/₄
Amount of cups of Strawberries = 2¹/₂
Amount of cups of Bananas = 1¹/₂
Amount of cups of Blueberries = 2¹/₄
Now, converting each of the given fractions to improper fractions gives;
11/4, 5/2, 3/2, 9/2
Summing up all the fractions will give us;
11/4 + 5/2 + 3/2 + 9/2
(1/4)(11 + 10 + 6 + 18) = 45/4
Now, since this total amount will be divided by 3, we will have;
45/4 ÷ 3
= 45/4 * 1/3
= 15/4 = 3³/₄ cups of fruit salad
