in a clinical trial of a new drug intended to treat asthma 4 of the 90 subjects in the treatment group experienced a cough and 12 of the 150 subjects in the control group had a cough. the difference is calculated to be significant at the 0.05 level. determine the meaning of this significant level
Homework Answers
At the 0.05 level of significance, the new drug is effective at reducing asthma symptoms.
As we testing a right-tailed test to see the new drug's effectiveness.
the test is significant at 0.05 level, we reject the null hypothesis and conclude that the new drug is effective at reducing asthma symptoms at 0.05 significance level.
