What does it mean for data to be skewed right?

• Data is skewed right when the tail on the right side of the distribution is longer or fatter than the left side.

• Data is skewed right when the tail on the left side of the distribution is longer or fatter than the right side.

• Data is skewed right when the mean is less than the median.

• Data is skewed right when all values are concentrated in the middle of the distribution.

What is the significance of the slope in a linear equation?

• The slope indicates the steepness of the line and the direction of the relationship between the variables.

• The slope represents the y-intercept of the equation.

• The slope determines the maximum value of the function.
