Question
It is claimed that the proportion of adults with at least one chronic disease in a certain country might be more than the reported number, which is only 25%. A random sample of 85 adults are surveyed, of which 28 are found to suffer from at least one chronic disease. Use a 0.01 level of significance to test the above claim. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard nomal distribution table. (a) Identify the null and alternative hypotheses. O A. H,: p= 0.25 against H,: p<0.25 O B. H: p#0.25 against H, : p= 0.25 OC. H: p= 0.25 against H,: p> 0.25 OD. Hp: p>0.25 against H,: p=0.25 O E. H,:p= 0.25 against H,: p 0.25 OF. H:p<0.25 against H,: p= 0.25 (b) Identify the critical region. (Round to two decimal places including any zeros.) O A. z< O B. z> OC. z< or z> (c) The z value for test can be calculated as (Round to two decimal places including any zeros.) (d) Make an appropriate conclusion. O A. Reject the null hypothesis because there is not significant evidence that more than 25% of the adults suffer from at least one chronic disease. O B. Do not reject the null hypothesis because there is not significant evidence that more than 25% of the adults suffer from at least one chronic disease. OC. Do not reject the null hypothesis because there is significant evidence that more than 25% of the adults suffer from at least one chronic disease. O D. Reject the null hypothesis because there is is significant evidence that more than 25% of the adults suffer from at least one chronic disease.
