Step by step solution

01

Given information

150 businesses were picked at random for a school's student newspaper survey about the value of students as clients. About 73 of them responded to the staff's inquiry. We must first determine the population and sample size.

02

Concept

A simple random sample (SRS) of size n is made up of n people chosen from the population with an equal chance of being the sample that is actually chosen.

03

Explanation

The poll is about local companies as well as the importance of students as clients, and it has received responses from 73 firms. The population refers to the entire group of people for whom data is required. As a result, the population is made almost entirely of local enterprises. A sample is a small portion of the population from whom data is gathered. As a result, the sample consists of the 73 businesses that responded to the questionnaire.

(a) using slips of paper.

(b) using Table D.

(c) using technology.

Two essential features of all statistically designed experiments are

(a) comparing several treatments; use the double-blind method.

(b) compare several treatments; use the chance to assign subjects to treatments.

(c) always have a placebo group; use the double-blind method.

(d) use a block design; use the chance to assign subjects to treatments.

(e) use enough subjects; always have a control group.

Eat well and exercise Most American adolescents don鈥檛 eat well and don鈥檛 exercise enough. Can middle schools increase physical activity among their students? Can they persuade students to eat

better? Investigators designed a 鈥減hysical activity intervention鈥� to increase activity in physical education classes and during leisure periods throughout the school day. They also designed a 鈥渘utrition intervention鈥� that improved school lunches and offered ideas for healthy home-packed lunches. Each participating school was randomly assigned to one of the interventions, both interventions, or no intervention. The investigators observed physical activity and lunchtime

consumption of fat.

Result: 鈥淥ur data suggest that the use of handheld cellular phones is not associated with risk of brain cancer.鈥�

(b) Based on this study, would you conclude that cell phones do not increase the risk of brain cancer? Why or why not?
