Mr 8. The results for an IQ quiz taken by 8 students from Ze Class A and Class B are shown below. The fal maximum score for the quiz is 25. we Class A: 4, 6, 6, 7, 8, 10, 11, 12 Class B: 0, 1, 1, 2, 3, 14, 17, 25 (i) Calculate the mean and standard deviation for Class A and Class B. Show your working clearly.

4000 B.C. A.D. 150 A study was done on skull sizes of humans during different time periods. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. H2 27 27 131.05 mm 133.94 mm S 5.18 mm 5.27 mm a. Use a 0.05 significance level to test the claim that the mean skull breadth in 4000 B.C is less than the mean skull breadth in A.D 150. What are the null and alternative hypotheses? O B. Ho: H1 =H2 O A. Ho: H1 =H2 H:H1> H2 OC. Ho: H1 = H2 H1: H1 # H2 O D. Ho: H1 # H2 H: H1

Is psychiatric history dependent on where the mother lives (country or city)? The test statistics for this hypothesis test are.... How to run t-test? which variable goes where? I attached images, is that correct and where to get the t statistic and p-value?
Consider the following sample data. Sample A: 11, 22, 33 Sample B: 81, 92, 103 Sample C: 1,100; 1,111; 1,122 (a) Find the mean and standard deviation for each sample. Sample A: Sample B: Sample C: Mean Sample Standard Deviation (b) What does this exercise show about the standard deviation? multiple choice The idea is to illustrate that the standard deviation is not a function of the value of the mean. The idea is to illustrate that the standard deviation is a function of the value of the mean.
10 An instructor of statistics claims that students in his section will score smaller than the students in a colleague’s section. The mean statistics score for 33 students in his section is 25.5 and the standard deviation is 4.1. The mean statistics score for 31 of the colleague’s students is 26.7 and the standard deviation is 4.5. At a = 0.01. Can the instructor’s claim be supported? According to this information the null and alternative hypotheses are: Select one: a. H0: μ1 ≤ μ2Ha: μ1 > μ2 b. H0: μ1 ≥ μ2 Ha: μ1 < μ2 c. H0: μ1 < μ2 Ha: μ1 > μ2 d. H0: μ1 > μ2 Ha: μ1 ≤ μ2
Consider the data set. 2, 4, 5, 6, 9 (b) Use the defining formula to compute the sample standard deviation s. (Round your answer to two decimal places.)
