Question: Part B: Exercise-4: Determining the Sample Size Use the following results for two independent random samples taken from two populations: Sample 1: N1=30 Mean1=10.36 Std.
Part B: Exercise-4: Determining the Sample Size Use the following results for two independent random samples taken from two populations: Sample 1: N1=30 Mean1=10.36 Std. Dev1=3.38 Sample 2: N2=32 Mean2=9.55 Std. Dev2=2.88 What is the point estimate of the difference between the two population mean? Provide a 95% confidence interval for the difference between two population's means. Background: http://www2.gsu.edu/~dscsss/teaching/mgs9920/slides/ch10.pdf
