Explanation:
I think your question is missed of key information, allow me to attach the photo question below.
The quantity demanded is 30 units when the price is 60, we use the reconciliation method on the demand line.
Based on the percentage of readers who own a particular make of the car and the random sample, we can infer that there is sufficient evidence at a 0.02 level to support the executive claim.
<h3>What is the evidence to support the executive's claim?</h3>
The hypothesis is:
Null hypothesis : P = 0.55
Alternate hypothesis : P ≠ 0.55
We then need to find the test statistic:
= (Probability found by marketing executive - Probability from publisher) / √( (Probability from publisher x (1 - Probability from publisher))/ number of people sampled
= (0.46 - 0.55) / √(( 0.55 x ( 1 - 0.55)) / 200
= -2.56
Using this z value as the test statistic, perform a two-tailed test to show:
= P( Z < -2.56) + P(Z > 2.56)
= 0.0052 + 0.0052
= 0.0104
The p-value is 0.0104 which is less than the significance level of 0.02. This means that we reject the null hypothesis.
The Marketing executive was correct.

Answer:
Return n investment = 11.67%
Explanation:
Return on Investment is the proportion investment that is earned as operating income.
For the division, the return on investment would be the proportion of te investment in assets that is earned as net income.
This would be determined as follows;
Return n investment = (Net income÷ Operating assets) × 100
Return n investment = (175,000 ÷ 1,500,000) × 100= 11.67%
Return n investment = 11.67%
Answer: (a) Fall
(b) Increase
(c) Increase
(d) Unchanged
Explanation:
Suppose there is a competitive market with a downward sloping demand curve and horizontal supply curve. In a competitive market there are large number of buyers and sellers. So, if there is a downward shift in the supply curve, as a result equilibrium price will fall, equilibrium quantity will increase, consumer surplus now become larger and producer surplus remains the same because of the horizontal supply curve.
