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.

Explanation:
Ticket Scalpers are the ticket speculators who buy the tickets to a sport or performance event and resells them at higher prices. Lassiez-faire economists consider it to be a good thing. the correct value of the ticker is decided by the market but the Scalpers are flexible in pricing than the venue, they may also bear a loss while still guaranteeing the full value that venue gets. But the problem with the scalping is the at the value goes to the <u><em>agents</em></u> instead of the venue that is providing the product.
