With the following p-values,would you reject or fail to reject the null hypothesis? Comment on the statistical significance of each result.(Assume you normally reject H0 at level 0.08.)
a.p-value = 0.0025
b.p-value = 0.0328
c.p-value = 0.0795
d.p-value = 0.1940
P-value
The probability of observing results as extreme as those observed in a study, under the assumption that the null hypothesis is true.
Null Hypothesis
A hypothesis in statistical analysis that assumes no significant difference or effect exists between specified populations or parameters.
Statistical Significance
An indication that the results observed in a study or experiment are unlikely to occur by chance alone, according to a predetermined threshold.
- Execute calculations of p-values and explain their roles in hypothesis test contexts.
