A random sample of patients who attended a clinic was selected. The age of the patient (years) (x) and the number of days since the last visit (y) were collected. The least-squares regression line for predicting number of days since the last visit from the age of the patient is y = 580 – 8.20x. If the predicted number of days for a patient since his/her last visit to the clinic is 190 days, find the patient’s age. Round your answer to the nearest integer.

Please write the answer legibly. Thank you. The age (X) and glucose levels (Y) of 6 patients are calculated in order to see if there is a relationship between these two variables. The following data was collected: SP xy = 478 SS x = 1241 SS y = 656 Calculate the correlation coefficient using the formula: r = SPxy / √ SSx SSy => [sq root of SSx SSy ] ---------------------------- Using the correlation coefficient (r) derived from above and...

The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, yˆ=b0+b1xy^=b0+b1x, 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 significant. Age 3535 4545...
