For the population of people who suffer occasionally from migraine
headaches, suppose 50% get some relief from taking ibuprofen. suppose we select a random sample of 84 people who suffer from migraines.
the probability that at least 60% of those in our sample will get relief from ibuprofen
a. 0.60
b. 0.97
c. 0.03
d. 0.52

The probability is 60% in our sample so we get relief from ibuprofen is 0.60

Step-by-step explanation:

From the given statement  as 84 is random sample and 50% got relief from i ibuprofen . The probability at least 60% so

60/100 = 0.60 value

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer is b
