Quality Assurance Department in the University applies a
statistical hypothesis test to determine if the average mark of the
purely online cohort is lower than the known average. Select all
that are true and can be determined from the information given.
Group of answer choices
At a significance level of 0.9 the probability of a Type 2 error
is 0.1
At a significance level of 0.1 the probability of a Type 2 error
is 0.1
A Type 1 error would be to conclude that marks have decreased
when they have not
At a significance level of 0.1 the probability of a Type 1 error
is 0.1
