Hello,
The answer would be D, because each strip represent 10 small squares out of 100.
Hope I Helped
ANSWER:
104
STEP-BY-STEP EXPLANATION:
Given:
Standard deviation (σ) = 700
Confidence level = 95%
Mean error (Eμ) = 135
We have for a confidence level of 95%:

Now, we calculate the minimum value of the sample size as follows:

The minimum sample size needed is 104
Answer:
The interpretation of that same problem is listed throughout the section below on explanation.
Step-by-step explanation:
Interpretation:
Researchers seem to be confident with 95% that the sample selection standard error seems to be + as well as - 4 percent respectively.
This same margin of sampling error would then decrease from either the mean or average value by four percentage points smaller or even larger, it describes the survey method.
Yw :)
