To find the relative frequency that people who prefer island vacations also prefer swimming, we need to divide the number of people who prefer island vacations and also prefer swimming by the total number of people who prefer island vacations.
So, the relative frequency of people who prefer island vacations and also prefer swimming is:
40/52 = 0.7692 or 76.9% (rounded to the nearest tenth)
Answer: 76.9%

Hunaruan looked across the fields his face was grave he sighed in despair "he maybe mighty he be great but in the end he will fate" He was suddenly awakened from his thoughts as a messenger approached.
"Lord Hunaruan" he said "the spys have returned Redworn King of the Redheads brings 10000 it is too great for us for our garrison only has 3900 "
"Were they caught" asked Pumperin who was standing next to Hunaruan.
"Yes" answered the spy " two died three survived one of which is wounded and now the redheads ride with all speed the spies only made it through a shortcut"
The spy shrieked and fell back. "Look" he cried "Redworn and his troops are coming to bring us doom"
Hunaruan looked back and saw Redworn and his Ten-thousand troops. He ran down the old ruined stairs and on to a lower battlement he looked at the ruins of this once great city all that remained untouched were the three great catapults.
"Perhaps these will bring us success" he thought. Then he cried aloud "sound the horn call for aid do not despair"
The horn sounded loud throughout the ruins of the city as the soldiers ran to their positions on the ruined walls some archers took their positionsns by the three catapults and others prepared giant boulders to fire through the great catapults the ruins were full of light as many torches were suddenly light. Hunaruan gazed out to the setting sun with Pumperin by his side he sighed and turned to Pumperin " if we are to die" he said "let us die defending this once great city" then he ran down the steps and on to the front battlements ready to face his enemy

North 120 125
South 25 75
Examine the data from a survey about the part of the state people are from and the fruit they prefer. Using relative frequencies, is the following statement true or false?
People from the North tend to like cherries more than grapes.
Enter 1 for true. Enter 2 for false.
To determine if the statement "People from the North tend to like cherries more than grapes" is true or false, we need to compare the relative frequencies of cherries and grapes in the North.
The total number of people from the North is:
120 + 125 = 245
The number of people from the North who prefer cherries is 120, and the number of people from the North who prefer grapes is 125.
So, the relative frequency of cherries in the North is:
120/245 ≈ 0.4898 or 48.98% (rounded to the nearest hundredth)
The relative frequency of grapes in the North is:
125/245 ≈ 0.5102 or 51.02% (rounded to the nearest hundredth)
Since the relative frequency of grapes in the North is greater than the relative frequency of cherries in the North, the statement "People from the North tend to like cherries more than grapes" is false.
Answer: 2 (false)
