The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 107107 pounds and a standard deviation of 39.339.3 pounds. Random samples of size 1818 are drawn from this population and the mean of each sample is determined.
1 answer:
Answer:
mean sample is 9.26
Step-by-step explanation:
Given data
mean = 107 pounds
standard deviation = 39.3 pounds
no of sample (n) = 18
to find out
sample means
solution
according to question we know mean of sample = 107 pounds
so standard error of this sample will be standard deviation /
now put all value n and standard deviation and we get sample mean i.e.
mean sample = standard deviation /
mean sample = 39.3 /
mean sample = 9.26
