Question

A proposition on the ballot needs more than 50% support in order to be approved. A random sample of 120 likely voters is taken, and 76 of them (63%) say that they support the proposition.


d) If we conduct a simulation in order to create a distribution of sample statistics, then the distribution will be centered at approximately:

  • 50%
  • 120
  • 63%


e) If we conduct a simulation in order to create a distribution of sample statistics, then the shape of the distribution will be approximately:

  • right skewed since 63% is more than 50%
  • left skewed since 50% is less than 63%
  • there is no way to know
  • normal (bell curve)
