To find the percentage of data values that are greater than or equal to 110, we need to look at the box-and-whisker plot. The box-and-whisker plot will show us the quartiles, median, minimum, and maximum values of the dataset.
If we look at the box-and-whisker plot, we can see that the box extends from approximately 80 to 120, which means that 50% of the data values are between 80 and 120. Since we want to find the percentage of data values that are greater than or equal to 110, we need to consider the upper quartile and maximum value.
From the plot, we can see that the maximum value is around 140 and the upper quartile is around 125. This means that 25% of the data values are between 110 and 125, and another 25% are between 125 and 140. Therefore, the percentage of data values that are greater than or equal to 110 is 25% + 25% = 50%.
So, the answer is 50% of the data values are greater than or equal to 110.
wrong
I apologize for the mistake in my previous response. Let's take another look at the box-and-whisker plot to correctly determine the percentage of data values that are greater than or equal to 110.
The box in the box-and-whisker plot represents the interquartile range, with the lower quartile (Q1) and the upper quartile (Q3) defining the middle 50% of the data. The line inside the box represents the median.
From the plot, if we can see that the whisker on the right side extends to approximately 150. This means that the maximum value in the dataset is around 150.
Since we want to find the percentage of data values that are greater than or equal to 110, we need to calculate the percentage of data values that fall between 110 and 150 (or are greater than or equal to 110).
To calculate this, we need to consider the values between the upper quartile (Q3) and the maximum value. Given that the upper quartile is 125 and the maximum value is 150, we can see that 25% of the data is between 125 and 150.
Therefore, the percentage of data values that are greater than or equal to 110 is 25%.
So, the correct answer is 25% of the data values are greater than or equal to 110.
