SD = Standard Deviation My Data: 2, 2, 2, 2, 5, 2, 5, 3, 2, 1, 2, 1, 6, 6, 5, 3, 2, 1, 4, 2, 4 a. Mean = 2.952, SD = 1.627 Team Data: 9, 4, 5, 5, 6, 12, 6, 8, 9, 10, 9, 8, 2, 9, 6, 6, 8, 9, 7, 4, 11, 3, 3, 8, 9, 7, 6, 4, 7, 4, 4, 8, 6, 5, 9, 12, 6, 10, 6, 11 Mean: 7.025, SD: 2.556916 Class Data: Split between black and gold team Gold team: Mean = 7.17, SD = 2.4 Black team: Mean = 9.93, SD = 2.45 3. Chose one of the members of your project team and complete a significance test at a significance level of 5% with the claim that your means are the same. 4. Then using the class data . . . which will be split into two groups (Black and Gold) . . . complete a significance test at a 5% significance (assume that the population standard deviation is 2.42) that the two groups have the same mean
