Answer:
15
Explanation:
165 divided by 11 is 15. For any number over 10 that you divide by 11, you can ignore the middle number and take the digit in the hundreds place and the digit in the ones place.
Answer: 1. A.Both firms will choose the low price.
2. B. Both firms would choose the high price.
Explanation:
1. If the firms cannot cooperate with each other and must choose simultaneously, both firms will choose the low price.
This is because at the low price both of them are at the highest profit they can make when they are not cooperating. For instance, if Firm B chooses Low Price and Firm A chooses High Price, Firm A will make $3 million while Firm be will make $8 million.
If Firm B decides to have a high price then firm A will take the low price and make $8 million in profit while Firm B makes $4 million. If they are not working together, they will both have to take the low price to make the most profit.
2. If the firms could cooperate with each other, both firms would choose the high price.
The is because they will be making more than competing and getting a lower profit. Should they cooperate they will each get $7 million in profit because they will pick the option they can both make the highest profit at. The is better than competing and making only $5 and $6 million respectively.

Answer:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
Explanation:
A confidence interval is a range of values, derived from the sample statistics, which may include the value of an unknown population parameter.
A 95% confidence interval indicates that between 152 of 160 samples (95%) of the same population will produce confidence intervals that will contain the population parameter.
It also means that we have a 95% confidence that the average (average amount) is among the resulting amounts obtained.
Logically, option "D" is missing the final part. This would be: D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $ 15.
This is the only true option, since the test is based on a sample of only 160 households, the entire population of households cannot be included.
Hence, the correct option is:
Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.
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.
