Suppose that a random sample of size 64 is to be selected from a population with mean 40 and standard deviation 5. (a) What is t
he mean of the xbar sampling distribution
1 answer:
Answer:
Sample mean (xbar) = 40
Step-by-step explanation:
Given that :
Sample size (n) = 64
Population mean (μ) = 40
Standard deviation (σ) = 5
The sample mean is equal to the population mean according to the central limit theorem.
The sample standard deviation = standard error = ;
Standard Error = σ / √n
Standard Error = 5 / √64
Standard Error = 5 / 8
Standard Error = 0.625

The answer of the given questions
a) 39 and b) 63
Step-by-step explanation:
Here are the solutions of given questions
a) 
=64-25
=39
b) 
= 36+27
= 63
Step-by-step explanation:
Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
