Answer:
A. We can select a lower confidence level and increase the sample size.
Step-by-step explanation:
The length of a confidence interval is:
Direct proportional to the confidence interval. This means that the higher the confidence level, the higher the length of the interval is.
Inverse proportional to the size of the sample.This means that the higher the size of the sample, the lower, or narrower, the length of the interval is.
Which of the following could we do to produce higher precision in our estimates of the population proportion?
We want a narrower interval. So the correct answer is:
A. We can select a lower confidence level and increase the sample size.
Answer:
5400
Step-by-step explanation:
so 90% of 850 is 765 (0.90x850)
765 is 10 years
so 1 year is 765/10 = 76.5 per year. So 76.5x59 = 4,513.5 add the initial ammount and you got 5,363.5 in the nearest hundredth you get 5400
To solve this all we need to do is multiply.
Since 1 kg is for $8, then we will multiply to see how much 16 kg would be for.
16 × 8 = 128
So, 16 kg is for $128.

The answer is 315 as the formula is : a+b/2•h.
Step-by-step explanation:
14/15 - 2/3 =
14/15 and 2/3 lcm is 15
so 14/15 becomes 14/15
- 2/3 become 10/15
15÷5=3 and 10÷5=2
so 14/15
-10/15=4/15
14-10 = 4
answer is 4/15 and since 15 can't be divided by 4 equally it is in simplest form at 4/15
