Question

A certain drug is used to treat asthma in a clinical trial of the drug 30 of the 288 treated subjects experience headaches (based on data from the manufacture)the accompanying calculator display shows result from test of the claim that less than 9% of treated subjects experience headaches use the normal distribution as an approximation to the binomial distribution and use a 0.01 significant level to complete part A through e below:

A) Is the test two tailed, left tail or right tail

B) what is the test statistics

C) what is the P-value

D) what is the null hypothesis, and what do you conclude about it?

E) decide whether to reject the null hupothosis

What is the final conclusion

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
