Answer: <u>The answer is A. $60,000 increase.</u>
<u />
Explanation: 1: The actual units sold multiplied by the budgeted sale price is equal to a total of $440000 (40000 x 11 = $ 440000)
2: The actual units sold multiplied by the actual sale price is equal to $500000 (40,000 x 12.5 = $ 500,000)
3:<u> $500000 - $440000 = </u><u>$60000</u><u> increase by the unit price factor.</u>

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.

A six-month moving average forecast is generally better than a three-month moving average forecast if demand: is rather stable.
