   Question

   Finally, Field described an example of a non-scientific study by a retail chain for an article in Marie Claire magazine, “shopping is healthy.” Women, on average, were said to walk for longer periods of time and cover more kilometres than men while shopping, which also burned more calories. Below is the correlation matrix of the relationships between distance (Distance: in kilometres), time spent shopping (Time: in minutes) and gender (Sex: 0 = male; 1 = female) of the (by Field simulated) data.

   

   Based on the above confidence intervals, are the following statements about the population likely?
   1: Women spend more time shopping than men do
   2: Women travel more kilometres while shopping than men do

   
   
   1. TRUE: statement 1 is; statement 2 is not
   2. FALSE: statement 1 is not; statement 2 is
   3. FALSE: both statements are
   4. FALSE: neither of these statements
   
   
   1. True
   2. False
   3. False
   4. False
