Answer:
14
Explanation:
Well if you see 15-8 is what we will have to do = 7 and 7+7 = 14.
The sampling distribution of the difference in sample means x⁻₁ - x⁻₂ is; 3.5 - 3.5 = 0
<h3>Difference in sample means</h3>
We are told that;
- A fair six-sided die, with sides numbered 1 through 6, will be rolled a total of 15 times.
- x⁻₁ represents the average of the first ten rolls.
- x⁻₂ represents the average of the remaining five rolls.
Now, the average of the largest and lowest numbers of the six sided die is;
E(x) = (6 + 1)/2 = 3.5
Thus, the average mean of the first ten rows is expressed as;
E(x⁻₁) = (n * E(x))/n
E(x⁻₁) = (10 * 3.5)/10
E(x⁻₁) = 3.5
The average mean of the last five rolls will be;
E(x⁻₂) = (n * E(x))/n
E(x⁻₂) = (5 * 3.5)/5
E(x⁻₂) = 3.5
Thus;
x⁻₁ - x⁻₂ = 3.5 - 3.5 = 0

Explanation:It gave a nation exclusive trade rights in a particular region of China. Helping them make a lot of money
To maximize its profit a monopolistically competitive firm would set marginal revenue to be equal to marginal cost.
<h3>What is a monopolistically competitive firm?</h3>
Monopolistically competitive firm is the description of the type of firm that exists in the market that have other firms that are having and offering similar products in the market.
The products may be similar but they are not identical. As a rule this type of market has to set MR = MC.
The difference between these firms and the true Monopoly is that this kind of firmss do not have the power to curtail supply so as to increase the prices in the market so they can raise their profits.
They do not have barriers to entry and the kind of profits that are made here are what we call normal profits. They are not price takers.
