Question
please show steps
3 Male crickets chirp by rubbing their front wings together, and their chirping is temperature dependent. The number of chirps per second for a cricket was recorded at 10 different temperatures. It is desired to predict the number of cricket chirps based on the temperature. To get Minitab to do this for you: Click on Stat, then regression, then fitted line plot. In the Response (Y): box, type the name of the appropriate variable. In the Predictor(X): box type in appropriate variable name. Select Linear under Type of Regression Model. Click OK a) What is the regression line? b) What is the correlation coefficient between temperature and number of chirps? c) What is the predicted number of chirps at a temperature of 26?Explanation / Answer
SolutionA:
From regresison output
chirps=6.894+0.3761(temperature)
slope of line=0.3761
y intercept=6.894
Solutonb:
r sq=79.86% given
=0.7986
r=sqrt(0.7986)
r=0.8936442
correlation coefficient=0.8936442
there exists a strong positive relationship between chirps and temperature
SOlutionc
we have
chirps=6.894+0.3761(temperature)
for temperature=26
=6.894+0.3761(26)
= 16.6726
=17
(rounding to nearest integer)
