Answer:
The answer is 91
Step-by-step explanation:
90 x 6 = 540
The numbers need to equal 540 all together to make an average of 90.
97 + 86 + 83 + 95 + 88 = 449
540 - 449 = 91
To check:
97 + 86 + 83 + 95 + 88 + 91 = 540
Therefore, the answer is 91
Answer:
Step-by-step explanation:
Given that IQ mean is 100 and std dev = 12 for normal adults
Std error = 
i.e. sample size should be atleast 97
The required sample size is 97.
This is reasonable as this is greater than 30
Yes. This number of IQ test scores is a fairly large number.
Given two points; (x₁,y₁) and (x₂,y₂) the slope is:
m=(y₁-y₂) / (x₁-x₂) or m=(y₂-y₁) / (x₂-x₁)
In this case:
(4,3)
(5,2)
m=(5-4)/(2-3)=1/-1=-1
Answer: the slope is -1
Is this a graphing question or…
