State

Make sure to state what your parameter (β) means in context!

Plan - One-sample t-test for β

Linear: Address your residual plot. Does the plot show a random scatter of points?

Independence: Is your sample size less than 10% of the population? (skip if sampling without replacement)

Normal: Address your residual plot. Is the population of residuals normally distributed? (no strong skew or outliers)

Equal SD: Address your residual plot. Is there roughly the same variability at each x value?

Random: Does your sample use random sampling or assignment?

Calculate

Make sure to draw a t-distribution curve, label it, and shade in the appropriate p-value.

Conclude

Please remember to put your conclusion and all parameters in context!
