Stells [14]

Complete Question:

Lenny asked 125 randomly chosen seventh grade students at his school to name their favorite beverage there are 1500 seventh grade students in the school predict the number of seventh grade students in his schoolwhose favorite food is pizza. 58 of the 125 students likes pizza.

Answer:

n = 696

Step-by-step explanation:

Sample size = 125

number of students out of the 125 that like Pizza = 58

Probability that a student will like pizza, P = 58/125

P = 0.464

Since there are 1500 seventh grade students in the school, based on the probability that a student likes pizza = 0.464, number of seventh grade students in the school that like pizza will be:

n = 100 * P

n = 1500 * 0.464

n = 696
