Question

question 1 of 10
which confidence level will produce the widest confidence interval, given a sample proportion of 0.7?
a. 68%
b. 95%
c. 90%
d. 96%

Explanation:

The width of a confidence interval depends on the critical value (z-score) associated with the confidence level. Higher confidence levels require larger critical values, which increase the margin of error and thus widen the interval. Among the options, 96% is the highest confidence level, so it produces the widest interval.

Answer:

D. 96%
