![**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 (e.g., 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:** [Textbox]
- **Standard deviation:** [Textbox]
**What is the probability that the sample of size 50 gives a sample proportion within 0.10 from the population proportion?**
