7 16
8 17
(1 point)
scatter plot A
The scatter plot shows a linear trend. As the height of the plant increases, the number of days increases.
scatter plot B
The scatter plot shows a positive trend. As the number of days increases, the height in centimeters increases.
scatter plot C
The scatter plot shows a negative trend. As the number of days increases, the height in centimeters increases.

11. Jake recorded the average temperatures for his hometown over a period of 20 days as shown in the chart below. He used the data to determine the mean temperature. In a report, he stated, ÒThe typical temperature in my hometown is about 62¡.Ó How is this statement misleading?
50¡ 58¡ 45¡ 61¡ 59¡
47¡ 94¡ 42¡ 48¡ 56¡
90¡ 94¡ 46¡ 59¡ 62¡
99¡ 55¡ 42¡ 46¡ 96¡
(1 point)
There are not enough data to decide what the typical temperature is.
The mean of the data is not about 62¡.
The mean is not misleading. The typical temperature is about 62¡.
The mean is not a good measure of the typical temperature because the temperatures are either really low or really high.

To make a scatter plot, you would need to:
1. Label the x-axis with the years and the y-axis with the distance thrown in meters.
2. Plot each pair of data as a point with the year on the x-axis and the distance on the y-axis.
3. Then connect the points with a line to show the trend in Christine's performance over time.
Here are the ordered pairs for each year:
(1997, 39.75)
(1998, 41.25)
(1999, 40.25)
(2000, 40.5)
(2001, 43.5)
(2002, 43.5)
(2003, 41.5)
(2004, 45.75)
And here's a link to a tutorial on how to make a scatter plot in Google Sheets: https://www.howtogeek.com/437269/how-to-make-a-scatter-plot-in-google-sheets/
I hope these resources help you create your scatter plot!
Height (in.) 54,56,58,61,63,65,70,71
Weight (ibs.) 100,110,122,135,146,150,170,171

```
In the scatter plot, the x-axis represents the height in inches and the y-axis represents the weight in pounds. Each dot represents a male student in Alice's class. There is a clear positive correlation between the height and weight of the male students, as taller students also tend to weigh more.
9. The answer is II.
10. The answer is A.
11. The statement is misleading because there are extreme high and low temperatures that may impact the accuracy of the mean temperature.
12. The answer is A.
13. The best display to identify the mode is a histogram with intervals of 5.
