A certain drug is used to treat asthma. In a clinical trial of the drug, 29 of 261 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 0.05 significance level to complete parts (a) through (e) below.

Answer
Final Answer: The test statistic, rounded to two decimal places, is \(\boxed{1.19}\).
Step 1 ：The test statistic is given in the table as \(z=1.191761618\). We need to round this to two decimal places.
Step 2 ：Final Answer: The test statistic, rounded to two decimal places, is \(\boxed{1.19}\).
