Project #32728 - math/stat

1) Use the "Weight and Height.xlsx" data (attached) Assume that the Weight and Height data is a sample data. Conduct analysis to answer the following questions:

A) What is the average height of the sampled students and its 95% confidence interval? What do these results tell us about the average height of the population?

B) What is the average height of the sampled students from KS and NE, respectively? Based on the two sample averages, do students in the two states differ in average height? 

 

 

2)  Watch this video clip about hypothesis testing and p value.After watching the clip, would you still rely on hypothesis testing for making statistical inferences? If your answer is yes, explain why. If your answer is no, explain why and discuss what would you do additionally or alternatively to help you make statistical inferences.
