a) The Qinl'ing panda is a subspecies of the Chinese giant panda, distinctly identifiable by its brownish coloration and patterning, as opposed to the familiar white and black of the majority of giant pandas. Qínl'ing pandas are endemic to the Qín mountains of central China, sometimes known as the Sichuan (or Szechwan) Alps, and experts believe that they compose no more than 13 percent of the wild panda population. As a conservationist working at the Chéngdu Panda Base, you want to put this estimate to test. Let p be the (true) proportion of Qínlıng pandas in the whole wild panda population. (i) Formulate appropriate null and alternative hypotheses. Explain briefly the rationale behind choosing the alternative that you did. (ii) Based on a random sample of 128 pandas, sampled randomly from all over the panda-inhabited region, of which only 15 were of the Qínl"ıng variety, carry out a test for the hypotheses in (i), reporting the p-value and your decision at 5% level of significance. Don't forget to carefully define the random variable you are using to carry out this test.

1) Parking at a XYZ university has become a very big problem. University administrators are interested in determining the average parking time of its students. An administrator inconspicuously followed 220 students and carefully recorded their parking times. The average parking time for the 220 students was 17 minutes. Jane Doe, one of the 220 students, took 19 minutes to find a a parking spot. Identity the following for the scenario above: a) Population b) Sample c) Parameter d) Statistic e) Variable t) Data
