![Sampling distribution of proportion :
The current recommendation for zinc is to have at least 30
mg/day. Assume that nationwide 60% of adult Americans
are zinc deficient. A random sample of 50 adult Americans
is selected.
Simplify up to three decimals ( ex: 1.121)
what is the sampling distribution of the sample proportion of
the adult Americans who are zinc deficient for a sample
of size 50?
sample proportion:
Standard deviation
what is the probability that the sample of size 50 gives
a sample proportion within 0.10 from the population
proportion?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F81d54a42-f02d-4bb3-a2f6-e94a0dae54f9%2F864c3de8-fe01-44c3-99f8-3eaba12b094b%2Fyu8k3g3_processed.png&w=3840&q=75)
