Step 1

True proportion estimate will be given by the ratio of success/favorable outcomes and the total sample size.

True proportion (in this case ) is calculated as shown below.

Step 2

Let sample proportion be denoted by p-hat. Confidence interval can be calculated using the formula shown below as long as there are atleast 5 successes (favorable outcomes) and 5 failures (unfavorabl outcomes) in the sample.

Step 3

Confidence interval: (0.555, 0.627) when confidence level is 90%

This would mea...
