Answer:

0.024

Explanation:

Sample size (n) = 146 people

The proportion (p) of people who answered that they would be interested in seeing the show again is:


p=(132)/(146)\\ p=0.9041

The standard error for a sample of size 'n' and proportion 'p' is:


SE = \sqrt{(p*(1-p))/(n)}\\SE = \sqrt{(0.9041*(1-0.9041))/(146)}\\ SE=0.024

The standard error for the sample proportion of audience members who want to see the show again is 0.024.
