When do crickets chirp more?

Computer Science Level pending

Here is a dataset describing the rate at which cricket chirps per second are heard in a secluded area, with respect to the temperature in Fahrenheit scale.

Using a linear regression model, predict the chirp frequency at 98° F. Enter your answer in s − 1 s^{-1}


The answer is 20.459.

#this part is better done with pandas
import csv
data = csv.reader(open('slr02.csv'))
for row in data:
     chirps.append(float(row[0]))
     temp.append([float(row[1])])

from sklearn import linear_model
regr = linear_model.LinearRegression()
regr.fit(temp, chirps)

print regr.predict([[98]])[0]

That gives 20.45950597882
