Osteoporosis is a condition where bones become weak. Because we use our dominant arm more than our nondominant arm, we expect the bone in our dominant arm to be stronger than the bone in our nondominant arm. By comparing the strengths, we can get an idea of the effect that exercise can have on bone strength. The strength of bones is measured in Newton meters divided by 1000 . Let $?=0.01$. Table 2. Strength of bones Questions 2A to 2D Answer the questions using the data in Table 2. 2A. Create a scatter plot for the data. 2B. Using either Microsoft Excel or your calculator, find the correlation coefficient, $r$. 2C. What does the value of $r$ indicate about the correlation between $x$ and $y$ ? 2D. Use either Table 11 or a hypothesis test (i.e. a t-test) to decide whether there is a significant correlation between $x$ and $y$ in the population.
