For each of 20 days, the graph shows City K's maximum temperature, in degrees Celsius, and average (arithmetic mean) relative humidity. A certain city activity was canceled for exactly two days, which are indicated by the black squares. The cancelation for one of those days was because the average relative humidity and maximum temperature were too high to safely conduct the activity, and the other cancelation was because of a rain storm.
From each drop-down menu, select the option that creates the most accurate statement based on the information given.
| Text Component | Literal Content | Simple Interpretation |
|---|---|---|
| Dataset Description | For each of 20 days, the graph shows City K's maximum temperature, in degrees Celsius, and average (arithmetic mean) relative humidity. | Each of the 20 points represents a single day, recording maximum temperature \((°\mathrm{C})\) and average humidity \((\%)\) for City K. |
| Cancellations Identified | A certain city activity was canceled for exactly two days, which are indicated by the black squares. | There are two specific days (marked with black squares) when the activity was canceled. |
| Reason for First Cancellation | The cancelation for one of those days was because the average relative humidity and maximum temperature were too high to safely conduct the activity, | One cancellation occurred due to dangerously high temperature and humidity. |
| Reason for Second Cancellation | and the other cancelation was because of a rain storm. | The other cancellation was due to a rainstorm rather than temperature/humidity. |
| Chart Element | Description | Interpretation |
|---|---|---|
| Chart Style | Scatter plot; two marker types | Data is presented as coordinate pairs; marker type gives extra info. |
| X-Axis | Temperature \((°\mathrm{C})\), \(15\) to \(33\) | Weather ranged from cool \((15°\mathrm{C})\) to hot \((33°\mathrm{C})\). |
| Y-Axis | Relative Humidity \((\%)\), \(0\) to \(100\) | Full spectrum of humidity measured. |
| Regular Days | \(18\) blue diamonds | These represent normal days with activity held. |
| Cancellation Days | \(2\) black squares at \(\sim 21°\mathrm{C}\), \(30\%\) and \(\sim 31°\mathrm{C}\), \(89\%\) | Days with canceled activity; one cool/dry, one very hot/humid. |
| Overall Pattern | Negative correlation between temperature and humidity | As temperature rises, humidity tends to fall on most days. |
The two days of cancellation have very different weather: one is extremely hot and humid \((31°\mathrm{C}, 89\%)\), likely canceled for safety/heat), and one is cooler and drier \((21°\mathrm{C}, 30\%)\), likely the rainstorm). Regular activity days avoid these extremes and tend to cluster in moderate ranges, showing that cancellations occurred only during atypical weather events.
The day the city activity was canceled because the average relative humidity and maximum temperature were too high to safely conduct the activity was on a day with a maximum temperature of ___ degrees Celsius.
The day the city activity was canceled because of a rain storm was on a day with an average relative humidity of ___ %.
By identifying which black square represents each cancellation, we found the heat/humidity day had a maximum temperature of \(31°\mathrm{C}\) and the rain storm day had an average relative humidity of \(30\%\). These answers match the available options.
Question 2 is dependent on correctly answering Question 1: once the heat/humidity cancellation day is identified, the remaining black square is for the rain storm. Thus, the answers are linked.
