Question

The drug Tamiflu (oseltamivir phosphate) is used to attack the influenza virus to reduce symptoms for patients.  The manufacturer label states that 6% of patients will develop nausea as a side effect.  Patients report that nausea occurs at a higher rate than the label indicates.  In clinical trials, among 724 patients treated with Tamiflu, 72 experienced nausea as a side effect. 

Using an α=0.05 level of significance, complete the following steps to determine whether the rate of developing nausea is higher than the manufacturer’s label.

(NOTE: All areas are reported to four decimal places; all z-scores are reported to two decimal places except the two special cases listed at the bottom of the table.)

Insert the following values from the question:

p = % =

q =

x =

n = 

p̂ = 

α = 

 Set up the hypothesis statements (no spaces between characters):
H0
H1
 
Based on the hypothesis statements, will you use α or (1 - α) to solve for zcrit
 
What is the value of zcrit
Use the appropriate formula to solve for ztest
Is the value of ztest further from zero than the value of zcrit?
Will you reject or fail to reject the null hypothesis? 
Does the study provide evidence that more than 5% of patients experience nausea?
