A biased sampling situation is described. In each case, give: (a) The sample (b) The population of interest (c) A population we can generalize to given the sample To determine the height distribution of female high school students, the rosters are collected from 20 randomly selected high school girls basketball teams.

Short Answer

Expert verified
The sample is the female players from 20 high school girls basketball teams, the population of interest is all female high school students, and the population we can generalize to is female high school basketball players.

Step by step solution

01

Identify the Sample

The sample refers to the specific group that has been chosen from the population to be studied. In the given scenario, the sample is the females players from 20 high school girls basketball teams since these are the one being used to determine the height distribution.
02

Identify the Population of Interest

The population of interest refers to the total set of individuals or items that the researcher is interested in studying. In our case, the population of interest is all female high school students, as we are interested in determining their height distribution.
03

Identify the Population that can be generalized to

This refers to a larger group that the sample data could be used to represent. In this instance, the population we can generalize to would be 'female high school basketball players' as the sample data consist of players from 20 high school girls basketball teams.

Following the steps given, design a randomized comparative experiment to test whether fluoxetine (the active ingredient in Prozac pills) is effective at reducing depression. The participants are 50 people suffering from depression and the response variable is the change on a standard questionnaire measuring level of depression. (a) Describe how randomization will be used in the design. (b) Describe how a placebo will be used. (c) Describe how to make the experiment double-blind.

Indicate whether we should trust the results of the study. Is the method of data collection biased? If it is, explain why. Send an email to a random sample of students at a university asking them to reply to the question: "Do you think this university should fund an ultimate frisbee team?" A small number of students reply. Use the replies to estimate the proportion of all students at the university who support this use of funds.

In Exercises 1.40 to \(1.45,\) state whether or not the sampling method described produces a random sample from the given population. The population is incoming students at a particular university. The name of each incoming student is thrown into a hat, the names are mixed, and 20 names (each corresponding to a different student) are drawn from the hat.

For the situations described. (a) What are the cases? (b) What is the variable and is it quantitative or categorical? Estimate the bending strength of beams by bending 10 beams until they break and recording the force at which the beams broke.

For the 2015 Intel Science Fair, two brothers in high school recruited 47 of their classmates to take part in a two-stage study. Participants had to read two different passages and then answer questions on them, and each person's score was recorded for each of the two tests. There were no distractions for one of the passages, but participants received text messages while they read the other passage. Participants scored significantly worse when distracted by incoming texts. Participants were also asked if they thought they were good at multitasking (yes or no) but "even students who were confident of their abilities did just as poorly on the test while texting." 15 (a) What are the cases? (b) What are the variables? Is each variable categorical or quantitative? (c) If we create a dataset of the information with cases as rows and variables as columns, how many rows and how many columns would the dataset have?
