t statistic equation
estimated regression coefficient - hypothesized value/coefficient standard error
degrees of freedom for t statistic
n - k - 1
most common hypothesis test done on regression coefficients
null hypothesis is equal to 0
k =
number of regression coefficients in the regression
smallest level of significance for which the null hypothesis can be rejected
p value
p value is LESS than significance level
reject null
p value is GREATER than significance level
don’t reject null
