Answer: A. Mean of sampling means 
Standard deviation of sampling means =
B. The probability that your sample has mean less than 165 is 0.1492 .
Given : The distribution of blood cholesterol level in the
population of young men aged 20 to 34 years is close to normal with
mean 
Mg/dl and standard deviation 
mg/dl.
Sample size : n= 150
Let 
sample mean values.
A. The mean and the standard deviation of the distribution of the sampling means would be :
Mean of sampling means =
Standard deviation of sampling means = 
The probability that your sample has mean less than 165 would be
Hence , the probability that your sample has mean less than 165 is 0.1492 .
Answer:
Blue grape in most expensive
Step-by-step explanation:
Given:
Amount of blue grapes = $18
Number of blue grapes = 4 bags
Amount of green grapes = $6.04
Number of green grapes = 2 bags
Find:
Which grape in most expensive
Computation:
Cost of blue grapes = 18 / 4
Cost of blue grapes = $4.5
Cost of green grapes = 6.04 / 2
Cost of green grapes = $3.02
Blue grape in most expensive
The answer to 3 is C, because 18+15 is 33, and 33 divided into three equal groups would have 11 in each.
The answer to 4 is A, because in 11/3 3 can go into 11 3 times, with 2/3 remaining.
