Name the 2 Hypothesis
null hypothesis and alternative hypothesis
μ and P is
test statistic (θ)
Type 1 error rate i quantified by
significance level also called alpha
significance level is…
the probability of rejecting
null hypothesis when its actually true.
The test statistic depends on…
the kind of test being done: for example, a t-test, a Chi-square test, or an F-test.
test statistic
Z Score=ztest
T Score = T Test
F=ANOVA
Chi-Square Statistic (x2)=Chi-Square test
μ (mu) and 𝑝 can be called?
parameters (θ)
Type I error
The type of error where you reject 𝐻0 when it is true is called a type I error (read: “type one error”) or a false positive.
Type II Error
Similarly, the type of error where you fail to reject 𝐻0 when it is false is called a type II error (read: “type two error”) or a false negative.
A one-sided test the H0 is?
H0:θ≤0
