A and c because jack knows how to do his work
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:
$575
Explanation:
Given that,
Opening office supplies = $1,100
Closing office supplies = $475
Office supplies expense for the month = $1,200
Opening stock + Purchases - Closing stock = Consumption
$1,100 + Purchases - $475 = $1,200
$625 + Purchases = $1,200
Purchases = $1,200 - $625
= $575
Therefore, the amount of office supplies was purchased during February is $575.
