Survey asking students whether they have visited Alaska, Hawaii, or both.

| | Alaska | Not Alaska | Total |
|------------|--------|------------|-------|
| Hawaii | 6 | 15 | 21 |
| Not Hawaii | 8 | 21 | 29 |
| Total | 14 | 36 | 50 |

1. What is the relative frequency for students who have been to Hawaii but not Alaska? [tex]$\square$[/tex]
2. What is the relative frequency for students who have not been to Alaska or Hawaii? [tex]$\square$[/tex]



Answer :

Sure, let's go through each of the questions step by step.

### Part 1: Relative Frequency for Students Who Have Been to Hawaii But Not Alaska

We need to find the relative frequency for students who have visited Hawaii but not Alaska.

1. From the table, identify the number of students who have been to Hawaii but not Alaska. This value is [tex]\( 15 \)[/tex].

2. The total number of students surveyed is [tex]\( 50 \)[/tex].

3. The relative frequency is calculated as:
[tex]\[ \text{Relative frequency} = \frac{\text{Number of students who have been to Hawaii but not Alaska}}{\text{Total number of students}} \][/tex]
Substituting the values we get:
[tex]\[ \text{Relative frequency} = \frac{15}{50} = 0.3 \][/tex]

So, the relative frequency for students who have been to Hawaii but not Alaska is [tex]\( 0.3 \)[/tex].

### Part 2: Relative Frequency for Students Who Have Not Been to Alaska or Hawaii

We need to find the relative frequency for students who have not visited either Alaska or Hawaii.

1. From the table, identify the number of students who have not been to Alaska or Hawaii. This value is [tex]\( 21 \)[/tex].

2. The total number of students surveyed is [tex]\( 50 \)[/tex].

3. The relative frequency is calculated as:
[tex]\[ \text{Relative frequency} = \frac{\text{Number of students who have not been to Alaska or Hawaii}}{\text{Total number of students}} \][/tex]
Substituting the values we get:
[tex]\[ \text{Relative frequency} = \frac{21}{50} = 0.42 \][/tex]

So, the relative frequency for students who have not been to Alaska or Hawaii is [tex]\( 0.42 \)[/tex].
