Select all that apply.
A.
There is a cluster of days when it rained between Days 6 and 15.
B.
There were three days of the month when it rained exactly 27 millimeters.
C.
There is an outlier at Day 26.
D.
There is a gap of no rain falling between Days 10 and 26.
E.
The greatest difference in the recorded amounts of rain in the city during the month was 3 millimeters.

Answer 1

I can’t see the scatter plot from the “LOADING…” text. Please either upload the plot image or type the list of plotted (day, mm) points.

Meanwhile, here’s how you can check each statement yourself:

- A (cluster Days 6–15): true if many points are concentrated between x = 6 and x = 15 (regardless of their y-values). Count points in that x-interval and compare to other intervals.
- B (three days with exactly 27 mm): true if there are exactly three plotted points with y = 27. Count the markers on that horizontal line.
- C (outlier at Day 26): true if the point at x = 26 is isolated far from the rest of the points (visually distant in y or x).
- D (gap of no rain between Days 10 and 26): “no rain” means y = 0. This is true only if every day with 10 < x < 26 has y = 0 (or there are no plotted points with y > 0 in that x-range). If the plot shows some nonzero y in that interval, D is false.
- E (greatest difference was 3 mm): compute max(y) − min(y). If that difference equals 3 mm, E is true; otherwise false.

If you upload the scatter plot image or paste the data points, I’ll mark which statements are true.
