Question description

With z test problems, you are given sample data, and population data (μ, σ, and normal distribution). The analysis focuses on determining whether it is reasonable to consider the sample a random sample from the population. Let's do a bare bones problem for practice.

Is it reasonable to consider a sample of 50 scores with

Xobt = 12.5 to be a random sample from a population of scores that is normally distributed, with μ = 15.0 and σ = 12? Use α = 0.052 tail in making your decision.zobt=___ zcrit=___
