A research center project involved a survey of 846 internet users. It provided a variety of statistics on internet users. (a) The sample survey showed that 91% of respondents said the internet has been a good thing for them personally. Develop a 95% confidence interval for the proportion of respondents who say the internet has been a good thing for them personally. (Round your answers to four decimal places.)

95% Confidence interval:  (0.8907,0.9293)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 846

Proportion of respondents who said the internet has been a good thing for them personally = 91%

95% Confidence interval:

Putting the values, we get:

(0.8907,0.9293) is the required 95% confidence interval for the proportion of respondents who say the internet has been a good thing for them personally.
