Answer:
C. Proofreading
Explanation:
Option A is wrong. In an instant message, no one is trying to create a content outline as it is not a letter or assignment.
Option B is incorrect. An instant message can be sent to many people at a time. Therefore, maximizing the number of receivers is the main idea while writing an instant message.
Option D is also not correct. Acronyms are hard to understand. Writing acronyms in an instant message will be challenging for the receivers.
Option E cannot be the answer as an instant message can be sent anytime. Therefore, it can be increased.
<em>Option C</em> is correct because while writing an instant message, proofreading is a necessary stage. If anything misspelled or miswritten, the explanation will change.

Occur at least annually

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.
Answer:
$5
Explanation:
The computation of Alice's consumer surplus is shown below:
Consumer surplus = Willing to spend - Market price after considering the discount
where
Willing to spend = $30
Market price equals to
= Purchase a pair of jeans - coupon rate
= $35 - $10
= $25
So, the consumer surplus is equal to
= $30 - $25
= $5
