I am conducting a research study.  I have two populations. Sample population 1 is a control group. Sample population 2 has received the intervention.

The question is, how do I determine if there is a relationship between the two populations using the data sets below:

  • Sample from Population 1: 33, 29, 35, 39, 39, 41, 25, 33, 38
  • Sample from Population 2: 46, 43, 42, 46, 44, 47, 50, 43, 39

Consider two populations. A random sample of 28 observations from the first population revealed a sample mean of 40 and a sample standard deviation of 12. A random sample of 32 observations from the second population revealed a sample mean of 35 and a sample standard deviation of 14. (a) Using a .05 level of significance, test the hypotheses !H0 : μ1 − μ2 = 0 and !H1 : μ1 − μ2 ≠ 0, respectively. Explain your conclusions. (b) What...

The results of sampling independent populations: sample 1 from population 1 • mean 1000 • sample standard deviation 400 • sample size 50 sample 2 from population 2 • mean 1250 • sample standard deviation 400 • sample size 50 Test the HO: population 1 mean = population 2 mean at alpha = 0.01. HA: population 1 mean =/ population2 mean. This is a two-tailed test with both a negative lower critical value and a positive upper critical value. Separate...

Two populations have mound-shaped, symmetric distributions. A random sample of 16 measurements from the first population had a sample mean of 20, with sample standard deviation 2. An independent random sample of 9 measurements from the second population had a sample mean of 19, with sample standard deviation 3. Test the claim that the population mean of the first population exceeds that of the second. Use a 5% level of significance. a) What distribution does the sample test statistic follow?...

I am trying to find an appropriate statistical test to run for a research study using someone else's gathered data (so that no IRB process is needed). In their data they present: Likelihood of Falling Asleep: Never 17 Seldom 22 Moderate 15 High 12 Use of napping during duty: Never 27 Rarely 19 Sometimes 16 Often 4 Both of these seem to be independent variables, but is there a way to show a relationship (or lack thereof) without a dependent...
