Looking for brainliest surveyed some of the employees at his company about their cell phone habits. from the data, he concluded that most employees at his company use cell phones primarily for business. for which sample could this generalization be valid?

a.

all managers in the company

b.

some managers and some sales executives selected at random

c.

every fifth employee on the employee list

d.

every other sales executive on the employee list

It is valid for answer choice C. This is because it is the only one that keeps the sample population perfectly random throughout all the positions in the company. Option A doesn’t consider any other employees but his stark tendency said “most employees”, which means everyone. B and D are also bad because of this reason: you can’t pick one specific group of people to sample and throw their results across everybody because different sample populations have different behaviors.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
