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

a) The 50% is equal to the the claimed value for the:

• population
• parameter
• sample
• statistic

b) The symbol for the claimed value of the population parameter, 50% is:

• p^
• x

c) The symbol for the observed statistic, 63%, is:

• p^
• x

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

• 63%
• 50%
• 120

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

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