Expert Solution & Answer

To determine

To explain: Whether the study is an experimental or non experimental study.

Answer to Problem 11P

The study is a non-experimental study as the researcher does not manipulates the variable under consideration.

Explanation of Solution

Given info:

600 eighth and ninth grade students were asked about their gaming habits and behaviour.

Moreover, adolescents who experienced more video game violence were also more hostile and had more frequent arguments with teachers.

Justification:

In the given study, the researcher does not manipulates the variable, gaming habits and behaviour of the students. That is, the researcher does not have control over the students. Therefore, manipulation of independent variables is not used. Also, group assignments are not random, therefore given example is a non-experimental study.

Two measurements are made of some quantity. For the first measurement, the average is 74.4528, the RMS error is 6.7441, and the uncertainty of the mean is 0.9264. For the second one, the average is 76.8415, the standard deviation is 8.3348, and the uncertainty of the mean is 1.1448. The expected value is exactly 75. 13. Express the first measurement in public notation. 14. Is there a significant difference between the two measurements? 1 15. How does the first measurement compare with the expected value? 16. How does the second measurement compare with the expected value?

In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.
