Ipsos conducted a poll for Global news in early January 2021 about the Coronavirus Vaccine requirements and found that 60% of Canadian adults (age 18+) would supporta Mandatory Vaccine policy.You want to see if this percentage has changed since then. You randomly select 400 adults and find that 258 of them supportaMandatory Vaccine policy.Is there enough evidence to conclude that the percentage of people who support a Mandatory Vaccine policy no longer equals 60%?Test the hypothesis at the 1% level of significance.

Part 1 (2 marks):What are the null and alternative hypotheses?

  1. H0: p = 60%HA: p 60%
  2. H0: p =60%HA: p <60%(pis less than 60%)
  3. H0: p =60%HA: p >60%(p is more than 60%)
  4. H0: p > 60%HA: p = 60%
  5. H0: p = 60%HA: p = 64.5%

Enter the LETTER of the correct answer

Part 2 (3 marks):

At the 1% level of significance, what is the critical value and decision rule?

Critical Value

Decision Rule

Calculate the value of the test statistic: (2 decimal places)

Part 4 :Decision with Justification

Part 5 (1 mark):Conclusion.

  1. Yes, there is enough evidence to conclude thatthe percentage of people who support a Mandatory Vaccine policy no longer equals 60%
  2. No, there is not enough evidence to conclude thatthe percentage of people who support a Mandatory Vaccine policy no longer equals 60%
  3. Enter the LETTER of the Number answer:
