Can you also provide explanations alongside work so I can understand how to do similar questions later on?
2) Thyroid stimulating hormone (TSH) in the population of individuals without thyroid disorders has a density with mean 2 mIU/L and standard deviation 0.64 mIU/L.
a. Do you have enough information to compute
(at least approximately) the proportion of individuals in this
population who have TSH greater than 3 mIU/L? If so,
provide this value. If not, explain why.
b. Do you have enough information to compute
(at least approximately) the probability that the average TSH in a
random sample of 100 individuals from this
population will be greater than 2.1 mIU/L? If so, provide this
value and a justification. If
not, explain why.
