- Choose among the following: A. the prevalence of hypertension among the three towns are equal B. there has been a change in the prevalence of hypertension in the town of San luis C. the prevalence of hypertension in San Luis is equal to the prevalence in Galindo D. Ho = 0.15 Should the null hypothesis be focused on San Luis, since that was required of us? Thanks!The U.S. Department of Transportation, National Highway Traffic Safety Administration, reported that 77% of all fatally injured automobile drivers were intoxicated. A random sample of 50 records of automobile driver fatalities in a certain county showed that 33 involved an intoxicated driver. Do these data indicate that the population proportion of driver fatalities related to alcohol is less than 77% in Kit Carson County? Use ? = 0.10. State the null hypothesis H0 and the alternate hypothesis H. np? nq? What is the value of the sample test statistic? (Round your answer to two decimal places.) Find the P-value of the test statistic. (Round your answer to four decimal places.) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ?? Interpret your conclusion in the context of the application.
