Stats Unit 6 Part 1

Confidence Interval

We are C% confident that the interval ___ to ___ captures the ___ (parameter in context).

Confidence Level

If we select many random samples of the same size from the same population and construct a C% confidence interval for each sample, about C% of intervals would capture the ___ (Parameter in Context).

P-Value

Assuming the true proportion is ___ (Ho), then there is a ___ (P-Value) probability of observing a sample proportion of (Ha) or ___ (>, <, ≠).

P - Value =< alpha

Because P-Value of ___ is =< alpha, we reject Ho, convincing evidence of Ha.

P-Value > alpha

Because P-Value of ___ is > alpha, we fail to reject Ho, no convincing evidence of Ha.
