A published report claims that 35% of college students have used an online dating site or app.  Believing this claimed value is too low, a researcher surveys a random sample of n = 420 college students about their experiences with online dating sites and apps.  A total of 166 of the surveyed students indicate that they have used online dating sites or apps.   Use this information to conduct a hypothesis test at a significance (or alpha) level of 0.05.   What will the hypotheses be? Ho: Ha:   2. What is the sample proportion? Calculate this value below and round your answer to three decimal places. 3.Calculate the test statistic below, using the same formula that you used when answering Question 5.
