Chapter 7: Problem 2

In 2017 Pew Research Center polled 3930 adults in the United States and found that \(43 \%\) reported playing video games often on some kind of electronic device. a. Identify the population and the sample. b. What is the parameter of interest? What is the statistic?

Short Answer

Expert verified
a. The population is all adults in the United States and the sample is the 3930 adults polled by Pew Research Center in 2017. b. The parameter of interest is the proportion of all US adults who play video games often on some kind of electronic device. The statistic is the \(43\%\) of the polled adults who reported doing this.

Step by step solution

01

Identifying the Population

The population signifies the entire group of people or objects the study is concerned about. Here, the population refers to all adults in the United States.
02

Identifying the Sample

The sample comprises the subset of the population from which data is gathered. In this case, the sample refers to the 3930 adults who were polled by Pew Research Center in 2017.
03

Identifying the Parameter of Interest

The parameter of interest signifies the characteristic that is being measured or observed from the population. Here, the parameter of interest is the proportion of adults in the United States who reported playing video games often on some kind of electronic device.
04

Identifying the Statistic

The statistic signifies a measure that is gathered from the sample. In this instance, the statistic is the \(43\%\) of the 3930 polled adults who reported playing video games often on some kind of electronic device.

Most popular questions from this chapter

According to studies done in the 1940 s, \(29 \%\) of people dream in color. Assuming this is still true, find the probability that in a random sample of 200 independent people, \(50 \%\) or more will report dreaming in color. Start by checking the conditions to see whether the Central Limit Theorem applies.

In a simple random sample of 1200 Americans age 20 and over, the proportion with diabetes was found to be \(0.115\) (or \(11.5 \%)\). a. What is the standard error for the estimate of the proportion of all Americans age 20 and over with diabetes? b. Find the margin of error, using a \(95 \%\) confidence level, for estimating this proportion. c. Report the \(95 \%\) confidence interval for the proportion of all Americans age 20 and over with diabetes. d. According to the Centers for Disease Control and Prevention, nationally, \(10.7 \%\) of all Americans age 20 or over have diabetes. Does the confidence interval you found in part c support or refute this claim? Explain.

Four women selected from a photo of 123 were found to have a sample mean height of 71 inches ( 5 feet 11 inches). The population mean for all 123 women was \(64.6\) inches. Is this evidence that the sampling procedure was biased? Explain.

The standard deviation of all professional NBA basketball players is \(29.9\) pounds. A sample of 50 professional basketball players has a standard deviation of \(26.7\) pounds. which number is \(\sigma\), and which number is \(s\) ?

According to a 2017 article in The Washington Post, \(72 \%\) of high school seniors have a driver's license. Suppose we take a random sample of 100 high school seniors and find the proportion who have a driver's license. Find the probability that more than \(75 \%\) of the sample has a driver's license. Begin by verifying that the conditions for the Central Limit Theorem for Sample Proportions have been met.
