K In a July 2017 report, a research firm stated that 39% of people from a certain region reported being harassed while online. An AP Statistics student decided to conduct her own survey at her high school of 3,260 students. She randomly selected 239 students to be surveyed and 99 of them stated that they had been harassed online. Does her survey suggest that the problem is worse at her school than it is for a typical person in the region? Determine the appropriate hypotheses. Ho P HA P (Type integers or decimals.) The test statistic is z = (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State your conclusion. Use a = 0.05. the null hypothesis. There sufficient evidence to conclude that the proportion of students in the high school who were harassed while online is the proportion of people from the region being harassed while online.
