EXERCISE 4 Brain weight Total sleep (hrs/day) -358" A scientist studied the relationship between the number of hours per day an animal sleeps and the weight of its brain. He took a sample of 62 different type of animals and obtained data on brain weight and total hours of sleeping per day. Table below depicts the result of correlation analysis. (grams) Pearson Correlation Sig. (2-tailed) 1 Brain weight (grams) .006 62 58 Pearson Correlation Sig. (2-tailed) N *. Correlation is significant at the 0.01 level (2-tailed). a) State the value of the Pearson correlation coefficient and the type of correlation that exists between the number of hours per day an animal sleeps and the weight of its brain. -358" 1 Total sleep (hrs/day) .006 58 58 b) What happens to the number of sleeping hours as the brain of an animal gets heavier?
