Question

In July of 2013, 47% of Australians thought unemployment would increase.  Assume in a recent poll, 47 out of 100 said that they thought unemployment would increase.  Estimate the proportion of all Australians today who believe unemployment would increase using a 94% confidence interval.

A: Assumptions
• Since Select an answer information was collected from each object, what conditions do we need
