Answer:
21
Step-by-step explanation:
Using<em> Simple Random Sampling</em>, we can estimate the sample size by the formula
where
n = sample size
Z = the z-score corresponding to the confidence level 99.5%
S = the assumed standard deviation = 3 seconds
e = margin of error = 2 seconds
<em>It is worth noticing that the higher the confidence level, the larger the sample should be.
</em>
The z-score corresponding to a confidence level of 99.5% can be obtained either with a table or the computer and equals
Z = 3.023
Replacing the values in our formula
So the size of the sample should be at least 21.

Step-by-step explanation:
- Given that Chris spends 35% of his budget on rent for his apartment.
We need to write 35% as a fraction, percent, and a decimal.
35% as a fraction:
All we need is to divide 35 by 100 as 35 is basically the 35th part of 100 parts.
Thus, 35% as a fraction would be: 35/100
35% as a decimal:
All we need is to divide 35 by 100 and calculate the result such as:
35/100 = 0.35
Thus, 35% as a decimal would be: 0.35
35% as a percent:
35% is already mentioned as a percent.
Thus, 35% as a percent would be: 35%
