Question

identify any clusters, gaps, or outliers in the histogram. model year 2020 plug-in hybrid electric vehicles (histogram with x - axis driving range (in miles) and y - axis frequency). select all that apply. a. there is a cluster between 475 miles and 525 miles. b. there is a cluster between 475 miles and 575 miles. c. there is an outlier at approximately 675 miles. d. there is an outlier at approximately 325 miles. e. there is a gap between 475 miles and 625 miles. f. there is a gap between 225 miles and 275 miles. g. the histogram has no clusters, gaps, or outliers.

Explanation:

Brief Explanations
  • Cluster Analysis: A cluster is a group of data points with high frequency. Looking at the histogram, the bar between 475 - 525 (or around 500) has a high frequency (tall bar), so A is correct. B's range (475 - 575) includes lower - frequency bars after 525, so B is wrong.
  • Outlier Analysis: An outlier is a data point far from others. The bar at 200 - 250 has low frequency, but the bar at 650 has some frequency. However, the bar at 200 - 250 is relatively isolated? Wait, no, the gap between 225 - 275 (F) is a gap (no bars), and the bar at 200 - 250 is an outlier? Wait, no, let's re - examine:
  • The bar at 200 - 250 has frequency 2, then a gap between 225 - 275 (no bars), so F is a gap.
  • The cluster at 475 - 525 (A) because the bar around 500 is very tall.
  • The outlier: the bar at 200 - 250 (frequency 2) is isolated from the main cluster (starts at 300), so is there an outlier? Wait, option D says 325, but 325 is in 300 - 350 which is part of the main cluster. Option C says 675, but the last bar is 650. Wait, maybe I misread. Wait the x - axis is 200, 250, 300, 350, 400, 450, 500, 550, 600, 650. So the first bar is 200 - 250 (frequency 2), then a gap between 225 - 275? Wait 200 - 250, then next bar is 300 - 350. So the gap is between 225 - 275 (F is correct). The cluster: the bars from 300 - 500 have relatively high frequency, and the bar at 500 (475 - 525) is the tallest, so A is correct. The outlier: the bar at 200 - 250 (frequency 2) is an outlier? But option D is 325, which is in 300 - 350 (part of the cluster). Option C is 675, but the last bar is 650. Wait, maybe the outlier is at 200 - 250, but there's no option for that. Wait, let's check the options again:
  • Option A: Cluster between 475 - 525 (the tall bar at 500, so this is a cluster of high frequency) - correct.
  • Option F: Gap between 225 - 275 (between 200 - 250 and 300 - 350, no bars) - correct.
  • Wait, maybe I made a mistake. Let's re - evaluate:
  • Cluster: A cluster is a concentration of data. The bar at 500 (475 - 525) is very tall, so A is correct. B's range is 475 - 575, but after 525, the frequency drops, so B is wrong.
  • Gap: Between 225 - 275 (no bars between 200 - 250 and 300 - 350), so F is correct.
  • Outlier: The bar at 200 - 250 (frequency 2) is an outlier? But the options for outlier are C (675) and D (325). 325 is in 300 - 350 (part of the cluster), 675 is beyond 650 (no bar there). Wait, maybe the outlier is not present in the options as I thought. Wait, maybe the correct options are A and F? Wait, no, let's check the histogram again. The first bar is 200 - 250 (frequency 2), then a gap (225 - 275, no bars), then bars from 300 - 650. The cluster is at 300 - 500, with the tallest bar at 500 (475 - 525), so A is correct. The gap is between 225 - 275 (F is correct). Also, is there an outlier? The bar at 200 - 250 is an outlier because it's isolated from the main cluster (starts at 300). But the options for outlier: D is 325 (in the cluster), C is 675 (no bar). Wait, maybe the question's options have A, F, and maybe others? Wait, let's re - check the options:
  • A: Cluster 475 - 525: Correct, as the bar here is very tall (high frequency).
  • F: Gap 225 - 275: Correct, no bars between 200 - 250 and 300 - 350.
  • Wait, maybe I missed. Let's see the frequency: 200 - 250 (2), 300 - 350 (5), 350 - 400 (8), 400 - 450 (5), 450 - 500 (5), 500 - 550 (13), 550 - 600 (2), 600 - 650 (2), 650 - 700 (3). Wait, maybe the cluster is 475 - 525 (A) because 500 - 550 has frequency 13. T…

Answer:

A. There is a cluster between 475 miles and 525 miles, F. There is a gap between 225 miles and 275 miles
