What is the relationship between area and perimeter?

• Area measures the space inside a shape, while perimeter measures the distance around it.

• Area and perimeter are the same thing.

• Area is always larger than perimeter.

• Perimeter is only relevant for circles.

What is a random sample?

• A subset of individuals chosen from a larger population, where each individual has an equal chance of being selected.

• A group of individuals selected based on specific characteristics or criteria.

• A sample that is selected randomly but does not represent the larger population.

• A collection of data points gathered from a single individual.

What is the formula for the area of a trapezoid?

• A = 1/2 * (b1 + b2) * h

• A = b * h

• A = (b1 * b2) / 2

• A = (b1 + b2) * h

How do you estimate a population based on a sample?

• By using the average of the sample data to represent the population.

• By applying the proportion of the sample with a certain characteristic to the total population size.

• By counting the total number of individuals in the sample and multiplying by the population size.

• By assuming the sample is identical to the population without any calculations.

What is the importance of sampling in statistics?

• Sampling allows researchers to make inferences about a larger population without surveying every individual, saving time and resources.

• Sampling is used to collect data from every individual in a population.

• Sampling eliminates the need for statistical analysis.

• Sampling is only useful in qualitative research.

What is a fitness habit?

• A type of exercise that is done occasionally

• A fitness habit refers to regular activities or behaviors that contribute to physical health and fitness.

• A diet plan that is followed for weight loss

• A specific workout routine that lasts for a month

What is the median in a data set?

• The median is the average of all values in the data set.

• The median is the middle value when the data set is ordered from least to greatest.

• The median is the highest value in the data set.

• The median is the difference between the highest and lowest values in the data set.

How do you interpret a dot plot?

• A dot plot displays individual data points along a number line, allowing you to see the distribution and frequency of values.

• A dot plot is used to compare two different sets of data visually.

• A dot plot shows only the average of the data points without any individual values.

• A dot plot is a type of bar graph that represents categorical data.

How do you find the average of a set of numbers?

• To find the average, add all the numbers together and divide by the total count of numbers.

• To find the average, multiply all the numbers together and divide by the total count of numbers.

• To find the average, subtract the smallest number from the largest number.

• To find the average, add the largest number to the smallest number and divide by two.

How do you find the area of a circle?

• A = πr², where r is the radius of the circle

• A = 2πr, where r is the radius of the circle

• A = πd, where d is the diameter of the circle

• A = r², where r is the radius of the circle
