Question

Information about a sample is given. Assume that the sampling distribution is symmetric and bell-shaped.

p^ = 0.27 and the standard error is 0.10

use this information to give a 95% confidence interval

Answer 1

Answer #1

Confidence interval formula is,

Z critical value for 95% confidence level is =1.96 (by using Z table)

=>(0.074, 0.466)

Answer 2
