In July of 2013, Australians were asked if they thought unemployment would increase, and 47% thought that it would increase. In November of 2013, they were asked again. At that time 570 out of 1300 said that they thought unemployment would increase. At the 8% level, is there enough evidence to show that the proportion of Australians in November 2013 who believe unemployment would increase is lower than the proportion who felt it would increase in July 2013?P: PARAMETER     What is the correct parameter symbol for this problem?     Correct     What is the wording of the parameter in the context of this problem?     CorrectH: HYPOTHESES     Fill in the correct null and alternative hypotheses:     𝐻0: Correct Correct .47Correct     𝐻𝐴: Correct Correct .47CorrectA: ASSUMPTIONS     Since Correct information was collected from each object, what conditions do we need to check?     Check all that apply.     𝑛≥30 or normal population.𝑛(𝑝̂)≥10𝑁≥20𝑛σσ is known.𝑛(1-𝑝̂)≥10𝑛𝑝≥10σσ is unknown.𝑛(1-𝑝)≥10Partially correct     Check those assumptions:          1. 𝑛𝑝 = 611Correct which is Correct 10Correct          2. 𝑛(1-𝑝) = 689Correct which is Correct 10Correct          3.
