Dolly the sheep, the worlds first mammal to be cloned, was introduced to the public in 1997. In a pew research poll taken soon after Dollys debut, 63% of Americans were opposed to the cloning of animals. In a pew research poll taken 20 years after Dollys, 60% of thoes surveyed were opposed to animal cloning. Assume this was based on a random sample of 1100 Americans. Does this survey indicate that opposition to animal cloning has declined since 1997? Use 0.05 significance level. please show calculations for all 4 hypothesis testing steps and steps on Statcrunch or Mindtap.
