TopicHypothesis test of binomial distributions
TypeCalculate Type I error probability
DifficultyModerate -0.8 This is a straightforward recall question testing understanding of Type I error definition. Students only need to recognize that P(Type I error) equals the significance level α, requiring no calculation or problem-solving—just direct application of a fundamental statistical concept.
Spec5.05b Unbiased estimates: of population mean and variance

2 A binomial hypothesis test was carried out at the \(5 \%\) level of significance with the hypotheses $$\begin{aligned} & \mathrm { H } _ { 0 } : p = 0.6 \\ & \mathrm { H } _ { 1 } : p > 0.6 \end{aligned}$$ A sample of size 30 was used to carry out the test.
Find the probability that a Type I error was made.
Circle your answer.
