FS17-STT-200-Lecture 1 Course Home | Content | Course Tools | Assessments I communication IH Quiz 2-Quiz 0:47:22 Shelby Smith: Attempt 2 A company hopes to improve customer satisfaction, setting as a goal of no more than 5% complaints. A random survey of 350 customers found only 10 with complaints. Does this provide evidence that the company has reached its goal? An appropriate set of hypothesis is: Ho : p 0.05 HA : p = 0.05 Ho : p = 0.05 Ha : p * 0.05 O None of these answers Ho : p=0.05 Ha : p > 0.05 O Ho: p 0.05 Ha : p

Explanation / Answer

An appropriate set of hypothesis is:

H0 : p=0.05 HA : p>0.05

Since rejection of null hypothesis will imply that the company has not reached its goal, whereas, acceptance of it implies that there is no more than 5% complaints and hence the company has reached its goal.
