Answer with explanation:
Scientist Measures the heights of 25 oak trees.And Finds the mean of the height of 25 trees.
Inferential Statistics, is used to determine ,if the height of tree is measured again and again and it's mean is evaluated , are the means same in each trial.
So, Our main aim is to find the Variation in the values of means of different data sets and then draw the inference.
After calculating mean , suppose five times,the height of 25 oak trees, we can draw valid inferences,
1.Can find appropriate range of Mean values.
2. We can test hypothesis about the given data set ,that is the mean of height of 25 oak trees,and then either accept it or Reject it.
