Perform a chi-square independence test, provided the conditions for using the test are met. Researchers studied the bone mineral density (BMD) and depression of men aged 65 to 92 years. At the 1% significance level, do the data in the table (taken from a random sample) provide sufficient evidence to conclude that BMD and depression are statistically dependent for elderly men? Click on the icon to view the data table. What are the null and alternative hypotheses? O A. Ho: BMD is dependent upon depression in elderly men. H₂: Depression is dependent upon BMD in elderly men. B. Ho: Depression and BMD in elderly men are statistically dependent. H₂: Depression and BMD in elderly men are statistically independent. O C. Ho: Depression and BMD in elderly men are statistically independent. H₂: Depression and BMD in elderly men are statistically dependent. Find the test statistic. x² = Find the P-value.

Copy the data to Desmos to draw a scatterplot of the data. Make sure to adjust the years so they represent years after 1980. a) Is it better to model the data with a linear or with an exponential model? [Select an answer b) Use regression in Desmos to find an appropriate model for f. Make sure to check Log mode in the parameter window in Desmos if you are fitting an exponential model. f(t) Round the coefficients to 4 decimal places. Hint: Use the variablet from the drop down menu when entering the equation.
