Step 1

1 of 11We were given a situation where the sample proportion $\hat{p}$ of Indian adults who rated the Indian economy as improving is $\hat{p}=29\%$. This is from a survey done by Gallup Poll which involved $n=1500$ Indian adults.

We were then asked to compute for the $95\%$ confidence interval for the true population proportion $p$ where $p$ is the true proportion of Indian adults who rated the economy as 'Getting better'.
