For numbers 1 to 3: The thermal condition in a cave is critical for sustaining a bat
population. A sudden change in the temperature is related to deaths of bats in
hundreds. An attempt to measure the degree of association between the
temperature (in °C) and death toll (number of deaths) was done using 20 caves
with reported cases of massive death among bats. Assume that temperature and
death toll are bivariate normal. Given below is the R software output:

3. Which of the following is(are) TRUE about the test of significance on the
correlation coefficient?
O A. There is no sufficient evidence to say that there is a linear relationship between
recorded temperature and the death toll.
O B. There is sufficient evidence to say that there is a linear relationship between
recorded temperature and death toll.
O C. There is no sufficient evidence to say that death toll is linearly dependent on
recorded temperature.
O D. There is sufficient evidence to say that death toll can be predicted using recorded
temperature
