Sticking with Oxybravne as describe above. Consider a sample size (with replacement) of 35 used to estimate the proportion of its residents falling in to A-class. (a) What is the probability that your sample reveals an estimate of ˆp of: pˆ = 0.343?
(b) Now what if the sample size was effectively infinite, and sampling was with replacement. What would your answer be now?
(c) How would you describe ˆp given the original sample size of 35 ? Be sure to specify all that you are capable of specifying.
(d) Calculate the probability that the ˆp estimate obtained in a sample would exceed a value of 29.9 %

(b) what are the null and alternative hypothesis being tested? (c) what is the t-statistic you would use? write the general formula and the final calculation.(d) sketch a t-distribution, label your t-statistic and the probability you would be interested in:
