Four parties participated in 2018 Provincial election in Ontario; PC, NDP, Liberal, Green party. PC captured 40% of the vote, NDP 30%, Liberal 25%, and the Green party 5%. A survey of 1000 voters asked each to identify the party that they would vote for in the next election. These results were PC=425, NDP=252, Liberal=267, and Green party = 56. Can we infer at 2.5% level of significance that the voter support is going to change in the next election? For part (a), round your answers in the right column to 3 decimal places. (a) Fill in the table below. Party Observed Frequency O Expected Frequency E (0 - E) E PC NDP Liberal Green Party x2 = E- (0 - E) Totals E (b) State the null and alternative hypotheses, and identify which one is the claim.

(d) What is the critical value Xer = (e) Is the null hypothesis rejected? O Yes O No (f) Is the claim supported? O At 2.5% significance level, there is sufficient sample evidence to support the claim that the voter support is going to change in the next election. At 2.5% significance level, there is not sufficient sample evidence to support the claim that the voter support is going to change in the next election
