1. In July of 1997, Australians were asked if they thought unemployment would increase, and 47% thought that it would increase. In November of 1997, they were asked again. At that time 289 out of 650 said that they thought unemployment would increase. At the 5% level, is there enough evidence to show that the proportion of Australians in November 1997 who believe unemployment would increase is less than the proportion who felt it would increase in July 1997? a) Give the sample size. b) Give the level of significance. c) Give the null and alternative hypotheses. d) Give the p-value. e) Determine whether to reject or fail to reject the null hypothesis.
