A study of bone density on 5 random women at a hospital produced the following result. Suppose a significance level of a=0.02 to perform this hypothesis test. Age 33 Bone density 340 37 335 45 330 65 325 73 310 a. Draw a scatter plot of the data. b. Calculate Test- Statistic the significance of the correlation coefficient c. State the null and alternative hypothesis? d. Calculate the p-value? e. Do you reject or fail you reject the null hypothesis?...
The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, 9 = bo + bx, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically...
