Question

The Monterey Bay Aquarium began a survey program in 1985. What is the margin of error for the large sample 95% confidence interval?

A. Visitor demographic information
B. Use of social media
C. Opinions on the aquarium visit
D. Proportion of visitors over 65 using a mobile device

Answer 1

The margin of error cannot be calculated without the sample size and estimated proportion.

Step-by-step explanation:

The margin of error for a large sample 95% confidence interval depends on the sample size and can be calculated using the formula:

Margin of Error = Z * sqrt((p * (1-p)) / n)

where Z is the Z-score corresponding to the desired confidence level, p is the estimated proportion, and n is the sample size.

Since we don't have the sample size or the estimated proportion for the large sample, it is not possible to calculate the margin of error for the given options.
