Certain drug is used to treat asthma in a clinical trial of the drug 24 of 282 treated subject experienced headaches based on the data from the manufacturer the accompany calculator display results from a test of the claim that less than 11%

See below

Step-by-step explanation:

The test is one-tailed (left-tailed in this case) because you are trying to prove that the true proportion is less than the proposed proportion of 11%

The test statistic, z, is given to us as z=-1.34 when rounded to 2 decimal places.

The p-value, p, is given to us as p=0.0908 when rounded to 4 decimal places.

The null hypothesis is because the original claim was that the proportion was less than 11%.

Hope this helped! It's been a while since I've done Statistics, but I believe this is all correct.
