Answer:

a

The sample size is n = 621

b

Voters Relative Frequency Frequency

Romney 0.21 130

Huckabee 0.19 118

Guiliani 0.12 75

John McCain 0.10 62

Ron Paul 0.04 25

Fred Thompson 0.04 25

Duncan Hunter 0.01 6

Tom Tancredo 0.01 6

Undecided votes 0.28 174

Step-by-step explanation:

From the question we are told that

The number of voters is n = 621

The voter election aspirants and their relative frequency are

Romney , 0.21

Huckabee , 0.19

Guiliani , 0.12

John McCain ,0.10

Ron Paul , 0.04

Fred Thompson 0.04,

Duncan Hunter 0.01

Tom Tancredo 0.01

Undecided votes 0.28

This undecided vote is used to represent votes that did not count and it is obtained by subtracting the other relative frequencies from 1 (i.e 100%)

Generally the frequency is mathematically represented as

Romney , 621 * 0.21 = 130

Huckabee , 621 * 0.19 = 118

Guiliani , 621 * 0.12 = 75

John McCain 621 * 0.10 = 62

Ron Paul , 621 * 0.04 = 25

Fred Thompson 621 * 0.04 = 25

Duncan Hunter 621 * 0.01 = 6

Tom Tancredo 621 * 0.01 = 6

Undecided votes 621 * 0.28 = 174

So the table is
