Answer:
40° Fahrenheit
Explanation:
For an X-bar, the centre line is then average across all components. In this case, the average temperature across all 1150 bottles over 115 days will be 40° Fahrenheit as it is reported.
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:
Residual income= $36,000
Explanation:
Residual income is the income that is generated in excess of the minimum required rate of return, which in this case is 10%. Any income above 10% return is considered as residual income. In this case the investment is 1,800,000 and 10% of that is 180,000 (0.1*1,800,000). So any income made above $180,000 will be residual income. In order to find the residual income we subtract the minimum income required from the actual income.
In this case the minimum income required is 180,000 and the actual operating income is 216,000 so residual income=
216,000-180,000= $36,000
