Suppose we take a random sample of n students and find the number, x, who have taken a statistics course. Use a random number generator to find a 3 digit number (between 100 and 900) to represent "n" and then find a 2 digit number (between 10 and 99) to represent "x". Rewrite the first sentence of this problem with your values and give the URL of the random number generator you used.

Response 1: Use 1PropZInt to find a 90% confidence interval of the proportion of students who have taken a statistics course using a classmate's post. Interpret the confidence interval in a concluding sentence.

Response 2: Use 1PropZInt to find a 99% confidence interval of the proportion of students who have taken a statistics course using a classmate's post. Compare it to the 90% confidence interval. Is it wider or narrower? Explain why.
