I need help finding the answer
In the US about 46% of the population wear glasses or contact lenses. A sample of 85 people is taken. About how many people would you ecpect to wear glasses or contact lenses?
Do I multiply .46 to 85?
Right.
about 39
I have the exact problem BUT mine asks what are you asked to do and how do you check your answer
Yes, to estimate the number of people who would wear glasses or contact lenses in a sample of 85 people, you can multiply the percentage of the population that wears glasses or contact lenses by the sample size.
First, convert the percentage to a decimal by dividing it by 100: 46% = 0.46.
Then, multiply the decimal by the sample size: 0.46 * 85 = 39.1.
So, you would expect approximately 39 people in the sample of 85 people to wear glasses or contact lenses.
