I don’t understand what you’re trying to find! I think it cut off. If you were talking abt the multiplication it makes 52.3
Answer:
The probability that the mean is less than 110
P(x⁻<110) =0.5
Step-by-step explanation:
<u>Explanation</u>:-
Given the standard deviation of the Population' σ' = 1250
Given sample size 'n' = 350
The standard error of the mean determined by
Standard error =
by using normal distribution
cross multiplication 66.8z = x⁻-110
x⁻ = 66.81Z+110
P(x⁻<110)=P(66.81Z+110<110)
= P(66.81Z < 110-110)
= P(66.81Z<0)
= P(Z<0)
= 0.5- A(z₁)
= 0.5 - A(0) (here z₁=0)
= 0.5 -0.00
=0.5
<u>Conclusion:- </u>
The probability that the mean is less than 110
P(x⁻<110) =0.5
Her whole wall is 1=6/6 hence what's not white is 1-2/6=4/6=2/3.
2/3 of her wall is green.
