For students in a certain region, scores of students on a
standardized test approximately follow a normal distribution with
mean ?=531.5μ=531.5 and standard deviation ?=28.1σ=28.1. In
completing the parts below, you should use the normal curve area
table that is included in your formula packet.
(a) What is the probability that a single randomly selected
student from among all those in region who took the exam will have
a score of 536 or higher?

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
