Answer: 0.7471
Step-by-step explanation:
Given : The Intelligence Quotient (IQ) test scores for adults are normally distributed with a population mean of 
and a population standard deviation of 
.
Sample size = 50
Using formula 
, the z-value corresponding to x=98 will be:-
Z-value corresponding to x=103 will be:-
Using the standard normal distribution table for z-scores, we have
P-value = 
Hence, the probability we could select a sample of 50 adults and find that the mean of this sample is between 98 and 103 = 0.7471

Answer:
(7-5)
Step-by-step explanation:
According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.
Next would be [3+(2*2)]
Then, [3+4]
Then, -8/1
Then, -3(7)
So the question would be 4-8-21
Which gives you -25 as an answer.
I realize that you weren't asking for the whole thing but maybe there are follow up questions.
That means one box out of 100,000 boxes will have a chance of winning.
That means 1/100,000.
0.00001 or 0.001%
