The Turbine Oil Oxidation Test (TOST) and the Rotating Bomb Oxidation Test (RBOT) are two different procedures for evaluating the oxidation stability of steam turbine oils. An article reported the accompanying observations on x = TOST time hr and y = RBOT time min for 12 oil specimens. TOST 4200 3575 3750 3700 4050 2770 4870 4500 3450 2675 3750 3300
RBOT 370 340 375 310 350 200 400 380 285 220 345 280

Required:
Calculate the value of the sample correlation coefficient. Round your answer to four decimal places. r =

step-by-step explanation:

i think you should think about the question and not look online.

my acc plz

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
