Over twenty years, it was found that the number of doctors of medicine, MD (in thousands), in the United States can be approxima
ted by MD=(28,390+693t)/(85-t) where t=0 represents 1980. The number of doctors of osteopathy, DO (in thousands), can be approximated by DO=(776-12t)/(65-2t) .
Write an expression for the total number I of doctors of medicine (MD) and doctors of osteopathy (DO). Simplify the result.

Answer:
Step-by-step explanation:
Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.
-We calculate the probability of a mean of 3.4 as follows:
#First determine the z-value:
#We then determine the corresponding probability on the z tables:
Hence, the probability of obtaining a sample mean this large or larger is 0.0228
