6. A statistics senior high teacher believes that fewer than 20% of QNHS students answered the
online examination through google forms. He surveys 84 of his students and finds that 11 answered
the online exam. An appropriate alternative hypothesis is:
A. p = 0.20
B. p > 0.20
C. p<0.20
D. p < 0.20
To answer this question we should find out the sample proportion. "p={\\frac {11} {84}}\\approx0.13" or 13%. As we can see, it is much smaller than assumed 20%, so it is appropriate to put forward the hypothesis that p < 0.2
