Explain. Describe in detail the assumptions of statistical hypothesis testing?Does this data meet those conditions? If not, describe how you could collect data thatwould meet the required assumptions of statistical hypothesis testing. Also, formallyexpress the hypothesis and explain whether it is a one-tailed or two-tailed test. Lastly,what is the nullhypothesis?
