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)
