Question

iologists have determined that crickets make more chirping sounds in warmer colder temperatures. They claim they can tell the temperature by measuring the table below shows number of chirps (x) across a specific time interval and the es than in chirps. The numbers of e (y) Number Of Chirps (x) 20 31 36 37 46 . Temperaturely) 60 78 73 83 b. (5 points) What does your answer in (a) tell you about the relationship? Be specific. c. (10 points) Fit a line using Method of Least Squares Calculate the correlation between number of chirps and temperature.

Explanation / Answer

a)

b)

this means that the number of chirps is positively correlated with Temperature

that is when Temperature increases, number of chirps increase.

This is strong correlation

c)

y^ = -36.9349+0.9852*Temp

number of chirps temperature 20 60 31 66 36 78 37 73 46 83 r 0.951988272
