Q1) The table below gives chirping frequency for striped ground cricket and corresponding temperature.

Chirps / second	Temperature in degrees F
20.0	88.6
16.0	71.6
19.8	93.3
18.4	84.3
17.1	80.6
15.5	75.2
14.7	69.7
17.1	82.0
15.4	69.4
16.2	83.3
15.0	79.6
17.2	82.6
16.0	80.6
17.0	83.5
14.4	76.3

a) Make a scatter plot for data. Consider chirps/second be your x values (independent) and temperature in degrees Fahrenheit be your y values (dependent). Label suitably and turn in the hard copy with your work.

b) Based on scatter plot, what kind of correlation, if any, do you observe? Describe in detail.

c) Determine the value of correlation coefficient between these 2 variables?

r = ____

d) Interpret the value of correlation coefficient. Describe in detail.
