1. a sample of 40 individuals is randomly selected from a normal population with μ = 100 and σ = 25. those individuals are treated, and the treatment is expected to increase scores by 6.2 points. assuming a two-tailed hypothesis test with α = .05, what is the chance of making a type i error? (1 point)
2. continuing with this second scenario you have just determined the alpha level for a study that has these characteristics:
3. a sample of 40 individuals is randomly selected from a normal population with μ = 100 and σ = 25. those individuals are treated, and the treatment is expected to increase scores by 6.2 points. you use a two-tailed hypothesis test with α = .05 to see if the treatment is statistically significant.
4.based on this information, what is the power associated with the statistical test? provide your answer and show some work to potentially earn partial credit. remember, calculating power is a multi-step process. (1 point)

i had to tie all these questions together as it is one large question on my assignment
