3
A result is called “statistically significant” whenever
null hypothesis is true
p-value is less or equal to the significance level
alternate hypothesis is true
p-value is larger than the significance level
4

5
A Type I error means
the null hypothesis is true
the null hypothesis is true, but we mistakenly reject it

the null hypothesis is false, but we fail to reject it
6
A Type II Error occurs when the null hypothesis
is not rejected when the null hypothesis is true
is not rejected when the alternative hypothesis is true
is rejected when the alternative hypothesis is true
is rejected when the null hypothesis is true

the 68-95-99.7 rule
