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:
Total= $19.56
Explanation:
Giving the following information:
The basic direct labor rate is $12.00 per hour. Payroll taxes are 13% of the basic direct labor rate, while fringe benefits such as vacation and health care insurance, are $6.00 per hour.
<u>The direct labor standard rate per hour is calculated using the direct labor rate, the taxes and fringe benefits.</u>
Standard direct labor rate:
Direct labor rate= 12
Payroll taxes= (12*0.13)= 1.56
Fringe benefits= 6
Total= $19.56
Answer:
$12,620
Explanation:
Cost of Direct materials of Job 99 = $70 x 100 = $7,000
Cost of Direct labour of Job 99 = $5 x 100 = $5,000
Overhead Expenses of Job 99 = $62 x 10 = $620
Total job cost for Job 99 = 7000 + 5000 +620 = $12,620
