If Alpha is Given
a) Decide whether to reject or fail to reject the null
hypothesis
- If: p-value ≤ alpha level reject Ho
- If: p-value > alpha level fail to
reject Ho
b) Write an English language sentence summarizing your
findings. For example if the null is rejected you might write:
Example 1) Ho rejected (assuming alpha = 5%): Since the p-value of 0.0?% is less than 0.05, The
sample is statistically significant at the 5% level, therefore
we have sufficient evident to reject the null hypothesis and accept the alternative hypothesis that
Bubba's magic pills caused a weight loss in the adults who took them as percribed.
Example 2) Ho accepted: Since the p-value of 0.0?% is greater than 0.05, the
sample is not statistically significant at
the 5% level, therefore, we fail to reject the null hypothesis.
There is not sufficient evidence to accept the alternative hypothesis that
Bubba's
magic pills caused a weight loss in the adults who took them as percribed.
