Answer:
Step-by-step explanation:
Using central Limit Theorem (CLT), The sum of 100 random variables;
is approximately normally distributed with
Y ~ N (100 × ) = N ( 50, )
The approximate probability that it will take this child over 55 seconds to complete spinning can be determined as follows;
N ( 50, )
Using Chebyshev's inequality:
Let assume that X has a symmetric distribution:
Then:
where: ()
Answer:
Yes
Step-by-step explanation:
You can estimate 1/5 to 1/4 and 4/8 to 2/4 Therefore 1/4+2/4 is 3/4
