Here is where SALT displays thesample mean age and standard deviation for the two patient groups.Enter the mean age and standard deviation for these two groups in the table, rounded to three decimalplaces.Surgical Site Infection (SSI)Sample SizeMean AgeStandard deviationNo Infection2,67852.45652.45616.89116.89124153.82853.82815.85215.852Yes InfectionPart 3 of 6We need to verify the assumptions for using the two-sample t test for comparing two population means toanalyze this dataset.First, the two samples must be independent and randomly selected. The data were collected from 2,919surgeries and we have no reason to believe that this sample is not representative of the population of patientwho undergo this type of surgery and since a patient will either develop a surgical site infection or will notdevelop one, the two groups are independent. This indicates that the first assumption has beenhas been met.Second, the sample sizes generally should be 30 or larger. We have 2,678 patients with no SSI and 241patients with SSI. This indicates that the second assumption has beenhas been met. = mean Age of patients who do not develop SSI= mean Age of patients who do develop SSIH21-H2#1-2=0Use a significance level of a = 0.05.Part 5 of 6Recall our hypotheses and summary statistics.= 0Surgical Site Infection (SSI)Sample SizeMean AgeStandard deviationNo Infection2,67852.45616.891Yes Infection24153.82815.852In SALT click an the "Inferential Statictics" age
