Question
I need help finding out if this is Left, Right or a Two Tailed Test. Also need help finding the test statistic, P Value, the Null Hypothesis, whether to reject or fail to reject and to make a final conclusion. Thanks In advance.
A certain drug is used to treat asthma. In a clinical trial of the drug, 16 of 269 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 9% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.01 significance level to complete parts (a) through (e) below. Question Help 1-PropZTest prop <0.09 z= -1.749141993 p=0.0401332390 p=0.0594795539 n= 269 a. Is the test two-tailed, left-tailed, or right-tailed? O Left-tailed test Right tailed test. Two-tailed test b. What is the test statistic? (Round to two decimal places needed.) c. What is the P-value? P-value = (Round to four decimal places as needed.) d.
