when you have two independent populations, explain the similarities and differences between the test of hypothesis for the difference between the means and the confidence interval estimate for the difference between the means?
Describe two differences between interview and observation methods. Explain how and when to use these methods in Information system research
Consider the following data from a repeated-measures design. You want to use a repeated-measures t test to test the null hypothesis H_0: mu_D = 0 (the null hypothesis states that the mean difference for the general population is zero). The data consist of five observations, each with two measurements, A and B, taken before and after a treatment. Assume the population of the differences in these measurements are normally distributed. Complete the following table by calculating the differences and the...
what do you see are some major differences between marketing and sales? How would you describe the differences to someone you know in everyday terms?
We considered the differences between the reading and writing scores of a random sample of 200 students who took the High School and Beyond Survey in Exercise 5.21. The mean and standard deviation of the differences are x̄read-write = -0.545 and 8.887 points respectively. (a) Calculate a 95% confidence interval for the average difference between the reading and writing scores of all students. lower bound: points (please round to two decimal places) upper bound: points (please round to two decimal...
How do you identify the differences between a logarithmic expression, a logarithmic equation, and a logarithmic function? Each has its own related process. Specifically how do you determine what you need to do when faced with one of these problems in algebra?

When might you want to know the mean differences between two or more groups in banking? Please describe the situation, including how and why it would be used.
In a paired samples t test, explain the logic of difference scores (why do you need to find them to make conclusions about your research) and why do you compare it to a population mean often designated as zero (µ = 0)?
When the standard deviations are equal but unknown, a test for the differences between two population means has n − 1 degrees of freedom. True or False?
