Answer:
The minimum sample size is n = 75 so that the desired margin of error is 5 or less.
Step-by-step explanation:
We are given the following in the question:
Population variance = 484
Standard deviation =

Confidence level = 0.95
Significance level = 0.05
Margin of error = 5
Formula:
Margin of error =


Putting values, we get

Thus, the minimum sample size is n = 75 so that the desired margin of error is 5 or less.

Answer: 3:2
Step-by-step explanation:
the base ratio of unused tape to used tape is 24:16.
then we have to simplify,
both 16 and 24 can be divided by eight,
24 divided by eight is 3
16 divided by eight is 2
therefore, our simlpified ratio is 3:2

Answer:
Percentage: 115%
Decimal: 1.15
Fraction: 
Step-by-step explanation:
<u>Percentages, Fractions, and Decimals</u>
Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.
Now we express 115% as a decimal, simply dividing by 100:
115% = 115/100 = 1.15
To express it as a fraction, we simplify the division instead of calculating it:
115% = 
Simplifying by 5:
115% =
