Part 2: Even More Practice Conducting a Hypothesis Test It is claimed that the proportion of adults who use a mobile fitness app is 0.19. Believing a different proportion of adults use a mobile fitness app, a researcher surveys a random sample of 260 adults and finds the sample proportion who use a mobile fitness app to be 0.25. Use this information to conduct a hypothesis test at a significance (or alpha) level of 0.05. 10. What will the hypotheses be? Ho: Ha: 11. What is the test statistic? Please calculate this value below. 12. What is the P-value? 13. Given the P-value you determined to answer Question 12, should you reject or fail to reject the null hypothesis? Please explain. 14. Are the results of this hypothesis test statistically significant? Please explain why or why not
