Question

Bigger snakes weigh more.  Here is data comparing the length in centimeters to weight in grams of a certain species of snake.  Assume both variables follow a normal distribution.

  1. Test the claim of correlation at the α = 0.05 level of significance.  Find the P-value       
  2. Will the null hypothesis be rejected?      
  3. Round the regression equation to one decimal place and use it to predict the weight of a snake 42 cm in length.      
Length  80 32 61 19 25 45 46 76
Weight  211 65 75 20 80 125 65 150
