Question

One spring day, Kennedy noted the time of day and the temperature, in degrees

Fahrenheit. During that time, the temperature rose, stayed steady, and fell, at
different rates. On the set of axes below, Kennedy created a graph of temperature
over time.

Answer 1

Please find attached the required graph for the temperature time relationship

Explanation:

The parameters given are arranged in a tabular form as follows;

At

Time Temperature

6 a. m. 56° F

7 a. m. 59° F

8 a. m. 62° F

9 a. m. 66° F

10 a. m. 70° F

11 a. m. 74° F

12 p. m. 74°F

1 p. m. 74°F

2 p. m. 74°F

3 p. m. 74°F

4 p. m. 74°F

5 p. m. 74°F

6 p. m. 74°F

7 p. m. 71°F

8 p. m. 68°F

9 p. m. 65°F

10 p. m. 62°F

11 p. m. 61.5°F

12 a. m. 61°F

With the above table as the data points, the graph can be drawn

From Excel, The Mean temperature is approximately 68.1°F

The standard deviation is 6.079 °F
