Textbook Question

Percentages
b. In a Pew Research Center poll on driving, 58% of the 1182 respondents said that they like to drive. What is the actual number of respondents who said that they like to drive?

Verified step by step guidance

Identify the percentage of respondents who said they like to drive, which is 58%.

Identify the total number of respondents, which is 1182.

To find the actual number of respondents who like to drive, multiply the total number of respondents by the percentage (expressed as a decimal).

Convert the percentage to a decimal by dividing by 100. So, 58% becomes 0.58.

Multiply the total number of respondents (1182) by the decimal form of the percentage (0.58) to find the actual number of respondents who like to drive.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Percentage Calculation

Percentage calculation involves determining a part of a whole expressed as a fraction of 100. In this context, it is used to find the number of respondents who like to drive by applying the percentage (58%) to the total number of respondents (1182). The formula is: (percentage/100) * total number.

Sample Size

Sample size refers to the number of observations or respondents in a survey or poll. It is crucial for ensuring the reliability and validity of statistical results. In this question, the sample size is 1182, which represents the total number of people surveyed about their driving preferences.

Polls and Surveys

Polls and surveys are methods of collecting data from a sample of individuals to infer opinions or behaviors of a larger population. They are essential for understanding public sentiment on various topics, such as driving preferences in this case, where 58% of respondents expressed their liking for driving.
