Complete the following MATLAB Exercise. The attached file has instructions and questions 

Devise a null and alternative hypothesis, then perform a one sample z-test using alpha=0.05 if our class is taller or shorter than the average human in the United States. Graphically display your answer and statistically write up results. In addition, determine the effect size of this relationship and interpret.Notes:The average height of adults in the United States is 67.0±3.8 inches. (Note: this is a population SD)Calculate and interpret the effect size (use Cohen’s d):Cohen's d = (Msample - µpopulation) ⁄ σ)Devise a null and alternative hypothesis, then perform a t-test using alpha =0.05 if the students in our class that are born in warm weather months are taller or shorter than those born in cold weather months. Graphically display your answer and statistically write up results. In addition, determine the effect size of this relationship and interpret.Notes:Population SDs are unknown.Assume the northern hemisphere:Warm months = April, May, June, July, August, SeptemberCold months = October, November, December, January, February, MarchUse Cohen’s d effect size:Cohen’s d = (M2 - M1) ⁄ SDpooled) where SDpooled = √((SD12 + SD22) ⁄ 2)

Each year ​t​, the value ​V​ of the coin increases by 3%a. V​ = 105(0.03)​tb. V​ = 0.03(105)​tc. V​ = 105(1.03)​td. V​ = 105(3)​tThe student enrollment ​E​ of a high school was 1200 in 1990 and increased by 12% per year until 1998. Which exponential growth model shows the school’s student enrollment in terms of ​t​, the number of years since 1990?a. E​ = 12(1200)​tb. E​ = 1200(1.12)​tc. E​ = 1200(12)​td. E​ = 1.15(1240)tYou deposit $1500 in a bank account.
