Answer: 1 1/20
Step-by-step explanation:
1/2 / 5/8 + 1/4
=8/10 +1/4
=21/20
=1 1/20
Answer:
101, 3, 0.025, 0.7416
Step-by-step explanation:
Given that a random sample of n = 16 observations is selected from a population that is normally distributed with mean equal to 101 and standard deviation equal to 12.
As per central limit theorem we have
a) Mean of sample mean = 
Std deviation of sample mean = 
Mean = 101
Std dev =3.00
b) 
c) the probability that the sample mean deviates from the population mean μ = 101 by no more than 4.
=
The answer is -5.3. Hope this helps!! :-)
