Question

The senior class of a high school needs to decide where to go for their senior trip. They have four choices: A cruise, a camping trip, a snorkeling trip, or to the Great Wall of China.

Due to budget constraints they cannot survey all 800 people in the senior class so they randomly select 150 people from the class and ask them their preference. The table shows the results.

Using the sample results, estimate the proportion of the entire population that would like to take a cruise to Bermuda.

Answer 1

A

Explanation:

5 of the 150 want to take the cruise, so:

p = 5/150

p = 0.03

Answer A.

Answer 2

Option A

Explanation:

Due to budget constraints they cannot survey all 800 people in the senior class so they randomly select 150 people from the class and ask them their preference.

Out of 150 students, 5 want to go to cruise to Bermuda.

So, the proportion becomes:

`(5)/(150)=(1)/(30)`

= 0.033

So, option A is the answer.
