This is a confidence interval level question :
In a poll of 1000 adults, 341 said they were comfortable with technology. Construct a 95% confidence
I have attempted to solve this twice but I am doing something wrong.
Confidence interval:
The (1-α) % confidence interval for proportion p is given by,
Computing the 99% confidence interval for population proportion:
It was found that, 341 out of the 1,000 adults said that they were comfortable.
That is, n=1,000 and the sample proportion, p-hat = 0.341 (=341/1,000). The confidence level is 95%. Therefore, the significance level, α = 0.05 and the z value corresponding to α/2 is 1.96. The 95% confidence interval for population proportion is given by:
