1). Write the null and alternative hypothesis. Make sure you write the correct “formula” (Ho or Ha), noting whether it is directional or non-directional depending on whether the question calls for an increase/decrease or simply a change!
2). Tell me under what circumstances you, as a researcher, would be committing a Type I AND a Type II Error.
Airline passengers understandably do not like it when their flights are canceled or do not leave or arrive on time. In 1999, the average number of complaints about such things was 0.27 per scheduled flight. Some people believe that airline customers today complain more these days about canceled flights and late flights. Is this true?
Hypotheses:
Type I and Type II Error
Type I Error:
Explanation / Answer
Hypothesis:
H0: p 0.27
H1: p > 0.27
Type I and type II errors. ... In statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (also known as a "false positive" finding), while a type II error is incorrectly retaining a false null hypothesis (also known as a "false negative" finding).
So, i would be commiting a type 1 error if in actual compaints have not risen and i say they have risen.
