The distribution is not a standard normal distribution.
We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.
Mathematically:
E(X) = 0 and V(X) = 1
Given that;
- the mean which follows a normal distribution (X) = 4.5338 g, and
- the standard deviation SD(X) = 0.1039 g
As such, the distribution is not a standard normal distribution.
Therefore, we can conclude that the distribution is not a standard normal distribution.

Answer:
y = 541
Step-by-step explanation:
The mean is calculated as
mean = 
Mean of set A =
=
= 266
ratio between means = 7 : 12, then
mean of set B =
× 266 = 456 , thus
= 456 ( multiply both sides by 5 )
1739 + y = 2280 ( subtract 1739 from both sides )
y = 541
Answer:
smallest number of chickens= 3
Step-by-step explanation:
In this question the given formation is:
two chickens in front of a chicken
the total number of chickens are 3
two chickens behind a chicken
the total number of chickens are 3
a chicken between two chickens
the total number of chickens are 3
So, the smallest number of chicken that can be required to make this formation will be 3.
So, if we consider that the chickens are walking in a straight line, two (2nd and 3rd) chickens will be behind the 1st chicken, two chickens( 1st and 2nd) will be in front of the last (3rd) chicken and one (2nd) chicken is in the middle of two (between 1st and 3rd) chicken.
Answer:
115
Step-by-step explanation:
180-50=130
130/2=65
180-65=115
