Please answer this in order from 1-4. Ticker code comes from Pfizer: https://finance.yahoo.com/quote/PFIZER.NS/history?period1=1606780800&period2=1609372800&interval=1d&filter=history&frequency=1d&includeAdjustedClose=true

3. Take the mean and standard deviation of data set A calculated in problem 1 and assume that they are population parameters (U and O) known for the variable fish length in a population of rainbow trouts in the Coldwater River. Imagine that data set B is a sample obtained from a different population in Red River (Chapter 6 problem!). a) Conduct a hypothesis test to see if the mean fish length in the Red River population is different from the population in Coldwater River. b) Conduct a hypothesis test to see if the variance in fish length is different in the Red River population compared to the variance in the Coldwater population. 4. An experimental drug is being tested to see if it reduces blood sugar in patients suffering from diabetes. Each of seven patients will receive both the placebo and the experimental drugs (treatments given a month apart) for a two week period. The maximum blood sugar (measured every day) on the second week of treatment is recorded. The data obtained from such a study is shown below: Patient Placebo Exp. Drug Difference 125 127 -2 130 100 30 133 110 23 JOUAWN 122 87 35 150 102 48 156 140 16 145 146 -1 Mean 137.3 116.0 21.3 SD 13.1 22.1 18.5 Conduct a hypothesis test to determine whether the new experimental treatment is beneficial for treating diabetes (reduces blood sugar). IMPORTANT NOTE: Make sure you do the following: -State Ho and H, using notation for each hypothesis test conducted. -Use a = 0.05 for all hypothesis tests conducted. -Explain all results obtained for both hypothesis tests and confidence intervals. You can use Excel to calculate means and standard deviations but all other calculations have to be done by hand.Pts Homework 3 Ratings Opts 2 pts Criteria 1 pts to and Ha missing 1.5 pts Major mistakes in stating Ho and Ha Q1 Part & Ho and Ha 2 pts Ho and Ha stated with minor mistakes Both Ho and Ha stated correctly 3 pts Opts Missing 4.5 pts Incorrect approach 6 pts 5.5 pts Correct approach but with several mistakes Q1 Fart a Approach and calculations 6 pts Correct approach with minor cal Correct approach and no calculation mistakes Mistakes can ako be in using the table, incorrect degrees of freedom, using wrong table, etc 0 pts 1 pts Missing 2 pts 1.5 pts Incorrect conclusion Q1 Fart & Conclusion 2 pts Conclusion is for the most part correct Technically correct conclusion D pts 2 pts 1 pts Ho and Ha missing 1.5 pts Major mistakes in stating Ho and Ha Q1 Fart ho Ho and Ha 2 pts to and Ha stated with minor mistakes Both Ho and Ha stated correctly 3 pts Missing & pts 4.5 pts Incorrect approach 5.5 pts Correct approach but with several mistakes Q1 Fart be Approach and calculations 6 pts Correct approach with minor calculation mistalents) Correct approach and no calculation mistakes Mistakes can also be in using the table, incorrect degrees of freedom, using wrong table, car D pts 1 pts Missing 2 pts 1.5 pts Incorrect conclusion Q1 Part b.

Use your ticker code to obtain the closing prices for the following two time periods to obtain two data sets: March 2, 2021 to March 16, 202] Data set A February 16, 2021 to February 28, 2021 Data set B Take the closing prices from data set B and add 0.5 to each one of them. Treat data sets A and B as hypothetical sample level data on the weights of newborns whose parents smoke cigarettes (data set A}, and those whose parents do not (data set B). a) Conduct a hypothesis test to compare the variances between the two data sets. b) Conduct a hypothesis to compare the means between the two data sets. Selecting the assumption of equal variance or unequal variance for the calculations should be based on the results of the previous test. c) Calculate a 95% condence interval for the dimce between means. 2. Take data sets A and B and delete duplicated values such that each value is unique even when pooling the two data sets. Just like with the previous problem, treat data sets A and B as hypothetical data on the weights of children whose parents smoke cigarettes, and those whose parents do not, respectively. Conduct a Wilcoxon Rank-Sum test on the data
