Relaxing after work. The 2010 General Social Survey asked the question: "After an average work day, about how many hours do you have to relax or pursue activities that you enjoy?" to a random sample of 1130 Americans. A 93% confidence interval for the mean number of hours spent relaxing or pursuing activities they enjoy was [1.16, 1.84].

(a) Interpret this interval in context of the data: "There is a 93% chance that the average number of hours spent by Americans relaxing after an average day of work is between 1.16 hours and 1.84 hours."

(b) Suppose another set of researchers reported a confidence interval with a larger margin of error based on the same sample of 1130 Americans. How does their confidence level compare to the confidence level of the interval stated above? . Higher

(c) Suppose next year a new survey asking the same question is conducted, and this time the sample size is 2600. Assuming that the sampled standard deviation does not change, what will be the new margin of error of the 93% confidence interval constructed based on data from the new survey?

I have correctly answered a and b already. I just need help with C
