Before Surgical Removal of a Diseased Parathyroid Gland, Two Tests

Multiple Choice

Before surgical removal of a diseased parathyroid gland, two tests are often performed: the standard intact test and the turbo test. Both tests measure parathyroid hormone (PTH, in ng/L) , but the turbo test is very expensive. Researchers obtained data from both tests in a sample of 48 patients to predict turbo test results (y) from standard intact test results (x) . The published findings include a scatterplot showing a clear linear relationship and the following summary:
Y = 1.08x - 4.36 (r = 0.97; n = 48)
We want to test a hypothesis of no relationship between the two procedures, H₀: p= 0 versus H_a: p≠0.
What is the P-value for this test?

A) Less than 0.001
B) Between 0.001 and 0.01
C) Between 0.01 and 0.10
D) Greater than 0.10
