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:
$14,343.25
Explanation:
The computation is shown below;
For the first bank
The value of investment is
= $68,000 × 8% × 8 + $68,000
= $111,520
For the second bank
= $68,000 × (1 + 0.08)^8
= $125,863.25
So, the difference in these both amount should be
= $125,863.25 - $111,520
= $14,343.25
The marginal productivity of the first hour of studying is 15%.
<h3><u>
What is Marginal Productivity?</u></h3>
- The additional output, return, or profit generated per unit as a result of benefits from production inputs is referred to as marginal productivity or marginal product.
- Raw materials and labor are examples of inputs. According to the rule of decreasing marginal returns, the marginal productivity will normally decrease as production rises when a production element is improved.
- This indicates that for every extra unit of output produced, the cost advantage often decreases.
- Diminishing marginal productivity is often recognized in its most straightforward form when a single input variable exhibits a drop in input cost.
- For instance, a reduction in labor expenses during the car-manufacturing process would result in slight increases in profitability per vehicle.
Formula for Marginal Productivity = (Qn – Qn-1) / (Ln – Ln-1)
The total product value is divided by the difference in labor to determine the marginal product of labor.
