Answer:
2.263
Step-by-step explanation:
standard deviation of sample means = s/\sqrt{n}
Given
Standard deviation s = 16pounds
Sample size n = 50
Substituting
standard deviation of sample means = 16/\sqrt{50}
standard deviation of sample means = 16/7.071
standard deviation of sample means = 2.263
Hence the standard deviation of sample means taken from this population with a sample size of 50 is 2.263
