Answer with explanation:
A x% confidence interval interprets the percentage of certainty that a person can believe that the true population parameter.
It is also represented as Point estimate ± Margin of error
Confidence level is proportional to the Margin of error.
- As confidence level increases the error bound increases that makes the confidence interval broader.
- As confidence level decreases the error bound decreases , making the confidence interval narrower.
Answer: <em>Multiply the original price by the decimal form of the percent and subtract that from the original price.
</em>
<em>37*0.85=31.45
</em>
<em>37-31.45=5.55
</em>
<u><em>Answer: New price is $5.55</em></u>
You need to first add up the total cost which is 12.45, then find 6% of 12.45 which is .747 or rounded to.75.(tax) then you need to add it to get 13.20. so the tip was 13.20
