13.59 - 1.89 = 11.70
20 - 11.70 = 8.30
Answer:
Step-by-step explanation:
The formula for determining confidence interval is expressed as
Confidence interval
= mean ± z × s/ √n
Where
z is the value of the z score
s = standard deviation
n = sample size
a) The 95% confidence level has a z value of 1.96
The 99% confidence level has a z value of 2.58
Since 99% confidence level z value is greater than 95% confidence level z value, if we input it into the formula, it will result to a higher confidence interval. So changing from a 95% confidence level to a 99% confidence level would make a confidence interval wider.
b) The √15 is smaller than the √350. This means that if we make use of the formula, √350 will give a lower confidence interval than that of √15. Therefore, the confidence interval would be narrower changing from a sample size of 15 to a sample size of 350.
c) Applying the formula, a standard deviation of 15 pounds would result to a lower confidence interval than a standard deviation of 20 pounds. Therefore, the confidence interval would be wider changing from a standard deviation of 15 pounds to a standard deviation of 20 pounds.
So all you need to do in order to find the sum is add so 185+66=251
Answer: Yer dad a lesbian
Step-by-step explanation:
Gay mom ^2 *granny tranny= lesbian dad
1/2 is equivalent to 50%
3/4 is equivalent to 75%
75% > 50% (75% is larger than 50%)
75% = 3/4
The answer is 3/4
Hope the answer helps :)
