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.

KatRina [158]

Answer:

The answer is: Red Carpet should try to focus on niche market segments.

Explanation:

A niche market is part of a greater market, but its focus is set on very specific products. The niche market has very specific market needs that need to be targeted by very specific products.

Usually niche markets are targeted by high priced products since normal broad range products or services will not satisfy their specific needs. For example, vegan restaurants are more expensive than McDonald's or Pizza Hut.

Since niche markets are small, usually big multinational corporations don't pay attention to them.

netineya [11]

Answer:

The answer is option B) The Delphi technique is a useful way to gather opinions from experts who desire anonymity.

Explanation:

The Delphi method seeks to collate opinions from a diverse set of experts, and it can be done without having to bring everyone together for a physical meeting.

Since the responses of the participants are anonymous, individual panelists don't have to worry about the consequences of their opinions.

Consensus takes time since opinions are carefully analyzed, making the method very effective.

It is an exclusive process used to arrive at a group opinion or decision by surveying a panel of experts.

Experts respond to several rounds of questionnaires, and the responses are aggregated and shared with the group after each round.

The experts can adjust their answer each round, based on how they interpret the group response provided to them to assess.

The ultimate result is meant to be a true consensus of what the group thinks whilst retaining the anonymity of the respondents.
