Identify the statistic to used, the degree of freedom, and the critical values. 4.Using the latest in medical technology, an orthopedic doctor has developed a new surgical procedure that he believes is an improvement over the standardprocedure. He wants to study whether the mean recovery time of patients who have the new procedure is less than the mean recovery time of patients whohave the standard procedure.The doctor studies a random sample of 11 patients who have the new procedure and a random sample of 9 patients who have the standard procedure. (Thesesamples are chosen independently.) The doctor records each patient's recovery time (in days). The patients who had the new procedure have a sample meanrecovery time of 380.4 with a sample variance of 3189.7. The patients who had the standard procedure have a sample mean recovery time of 424.8 with asample variance of 469.2.Assume that the two populations of recovery tiìmes are approximately normally distributed. Can the doctor conclude, at the 0.05 level of significance, that thepopulation mean of the recovery times of patients who have the new procedure is less than the population mean of recovery times of patients who have thestandard procedure?Perform a one-tailed test. Then complete the parts below.Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)

The provided information is x¯1=380.4, x¯2=424.8s12=3189.7, s22=469.2n1=11, n2=9α=0.05 s1=56.47,…

For the project, you will have to: Collect and organize a sample of 30 items of data from a source you find relevant. Some examples: Sports (top HR hitters, rushing leaders, point scorers, etc.) Weather (average daily temperature for a month, max hurricane wind speed, etc.) Business (top-grossing movies, highest-paid athletes, record sales, etc.) Demographics (age, height, weight, etc.) Find the mean, median, mode, and mid-range for your date. Find the variance, standard deviation, and range for your data. Find the five-number summary and determine (mathematically) if there are any outliers. Construct a 95% confidence interval for the mean of your data. You are allowed to use the calculator for the calculations but you must provide me with the 30 data values you obtain in a neat, organized manner, preferably in a spreadsheet. Also, be sure to provide the source of your data. When you provide the answers to the questions above please use the correct symbols and notation.…
Cris Turlock owns and manages a small business in San Francisco, California. The business provides breakfast and brunch food, via carts parked along sidewalks, to people in the business district of the city. Being an experienced businessperson, Cris provides incentives for the salespeople operating the food carts. This year, she plans to offer monetary bonuses to her salespeople based on their individual mean daily sales. Her first task is to see if there is a significant difference in the mean daily sales among the different salespeople. She chooses a "sample" of days for each salesperson and records the sales for each day. She then runs a one-way, independent-samples ANOVA test to determine whether or not she can conclude that at least one salesperson's performances is significantly different from the others. (Otherwise, she'll split the bonuses evenly among all the salespeople.) In her ANOVA, the "groups" are the different salespeople, and the variable of interest is the daily sales…
UBS Wealth Management UK periodically ask their customers to evaluate their financial consultants and services. The higher the customer rating, the better the perceived service. The maximum rating is 7. Independent samples of two financial consultants are given below. Consultant A has 10 years' experience, Consultant B has 1 years' experience. Use α = 0.05 and test to see whether the consultant with more experience has the higher population mean service rating. Consultant A Consultant B N1 = 16 N2 = 10 Mean1 = 6.82 Mean2 = 6.25 S1= 0.64 S2 = 0.75 State the null and alternative hypothesis, Compute the value of the test statistic. What is the p-value? What is your conclusion?
