Question

in a survey at a local university, 63% of students say that they get less than the recommended eight hours of sleep per night. in a group of 3700 students, how many would you expect get eight or more hours of sleep per night? students get eight or more hours of sleep per night. (type a whole number.)

Explanation:

Step1: Find the percentage of students getting 8 or more hours of sleep

The percentage of students getting less than 8 hours of sleep is 63%. So the percentage of students getting 8 or more hours of sleep is $100 - 63=37\%$.

Step2: Calculate the number of students getting 8 or more hours of sleep

We have a total of 3700 students. To find the number of students getting 8 or more hours of sleep, we multiply the total number of students by the percentage (in decimal form). The decimal form of 37% is 0.37. So the number of students is $3700\times0.37 = 1369$.

Answer:

1369
