Answer:
Range: (844.9,1333.7)
A brain volume of 1348.3 cm cubed can be considered significantly high.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 1083.9 cm cubed
Standard Deviation, σ = 122.2 cm cubed
Range rule thumb:
- This rule state that the the range of data is four times the standard deviation of the data.

Upper Limit:

Lower limit:

Since, 1348.3 does not lie in the range (844.9,1333.7), a brain volume of 1348.3 cm cubed can be considered significantly high.
Answer:
E(X ¯)=210,000.
Step-by-step explanation:
A sampling distribution for samples of size n=49 from a population with means μ=210,000 and standard deviation σ=35,000, has the following means anda standard deviation:

If X ¯ is the mean sales price of the sample, it will have a mean value of E(X ¯)=210,000.
The answer is a) form questions because the scientist must first have a question or problem to solve for him to conduct the scientific process
Answer:
x = 3/2
Step-by-step explanation:
Simplify this equation by dividing all three terms by 1/4:
2x - 1 = 2, or
2x = 3
Then x = 3/2
