Hypothesis and P value

The pp value is the probability of observing a result by chance. 

 

The pp value calculated in this experiment is 0.03.

 

A pp value less than or equal to the critical pp value of 0.05 means the result is significant. 

 

This means we can reject the null hypothesis, which states there is no difference.

 

Therefore, a person’s resting heart rate does significantly affect their 100 mm sprint time.

The pp value is the probability of observing a result by chance. 

 

The pp value calculated in this experiment is 0.32.

 

A pp-value more than the critical pp value of 0.05 means the result is not significant. 

 

This means we can accept the null hypothesis, which states there is no difference.

 

Therefore, the phenotypic ratio of black eyes to red eyes matches the expected ratio of 3:1.
