The accompanying calculator display shows results from a test of the claim that less than 11% 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. 1-PropZTest prop <0.11 z- -1.7927e9560 p=0.0365032897 p=0.0748031496 n=254 a. Is the test two-tailed, left-tailed, or right-tailed? Two-tailed test Right tailed test V Left-tailed test b. What is the test statistic? z= -1.79 (Round to two decimal places as needed) c. What is the P-value?
