How does sample size affect the width of a confidence interval? We want to show that reaction time in students is greater than 175 milliseconds.
How does sample size affect the width of a confidence interval?
We want to show that reaction time in students is greater than 175 milliseconds. What are the correct hypotheses?
Group of answer choices
Ho: 175, Ha: < 175
Ho: 175, Ha: > 175
Ho: P = 175, Ha: P< 175
Ho: P 175, Ha: P > 175
When selecting a significance level, why should we consider the consequences of a type I error?
Why do we say that we "fail to reject" the null instead of saying "accept?"
