One million: 10^6
Ten million: 10^7
So the exponent will be anywhere between 6 and 7, inclusive
Answer:
a)
b) 
c) 
d) 
Step-by-step explanation:
Let X the random variable that represent the number of material anomalies occurring in a particular region of an aircraft gas-turbine disk. We know that
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this distribution the expected value is the same parameter
,
, 
a. Compute both P(X≤4) and P(X<4).
Using the pmf we can find the individual probabilities like this:




b. Compute P(4≤X≤ 8).







c. Compute P(8≤ X).


d. What is the probability that the number of anomalies exceeds its mean value by no more than one standard deviation?
The mean is 4 and the deviation is 2, so we want this probability





Hello!
To calculate mean absolute deviation, you find the mean, find the distance between each data point and the mean, add up those distances, and divide by the number of data points.
In this scenario, after Natalia finds the distances, she must add them all up and then divide by the number of data points.
I hope this helps!

If $2397 is 100%
and $685 is unknown
685x100=68500
68500/2397=28.5774
round to 29%
