In the 2000 presidential election, three candidates split the vote as follows:

Bush 47.9%

Gore 48.4%

Nader 2.7%

sample size

population proportion, or p

We will consider a vote for Al Gore a \"success.\" We can look back and select a random sample of 50 voters from the 2000 election and count the number of those who voted for Gore. Suppose in that sample 23 voted for Gore. Match the numbers above with the correct term.

Solution

a)

the sample size is the sample of 50 voters from the 2000 election

but as we need only the sample who voted for gore so, the sample size is 23

b)

population proportion or p

is the proportion of population that the problem give us at the begining

In the 2000 presidential election, three candidates split the vote as follows:

Bush 47.9%

Gore 48.4%

Nader 2.7%

so the proportion for voted for gore is p = 48.4% = 0.484

c)

and the sample proportion

is the proportion of the sample that voted for gore that is the number of voted for gore in the sample divided by the sample of voters from the 2000 election

p\'\' = 23 / 50 = 0.46
