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 to check? Check all that apply. o is unknown. o is known. On > 30 or normal population. | n(p) ≥ 10 On(1 − p) ≥ 10 ON>20n Check those assumptions: 1. np= 2. n (1 — p)= 3. N= which is ? ✓ which is ? ✓ which is ? ✓ If no N is given in the problem, use 1000000 ? ✓ = N: Name the procedure The conditions are met to use a Select an answer I: Interval and point estimate The symbol and value of the point estimate on this problem are as follows: Leave answer as a fraction.
