Answer:
The expected change in the number of electronics job in the city next year is of 140.
Step-by-step explanation:
We have these following probabilities:
20% chance it increases by 1000.
50% chance it increases by 300.
30% it decreases by 700.
Find the expected change in the number of electronics job in the city next year
We multiply each outcome by it's probability. So
E = 0.2*1000 + 0.5*300 - 0.3*700 = 140
The expected change in the number of electronics job in the city next year is of 140.
Answer:
- C) Use benchmark percent and find 50% of 146.7
Step-by-step explanation:
<u>Accurate estimation of 33% of 146.7</u>
A) Round the percent and find 30% of 146.7
- Acceptable, rounded down the %
B) Round the number and find 33% of 150
- Acceptable, rounded up the number
C) Use benchmark percent and find 50%
of 146.7
- NOT acceptable as 50% is too much for 33%
D) Round the percent and number and
find 30% of 150
- Acceptable, both % and the number rounded
E) All of them would be an accurate estimation
Answer:
As the probability of X less than or equal to 23.6474819 and the probability of X is less than or equal to -0.1909414, as the points are less than the condition, then there are unusual and equal to an unusual situation.
Step-by-step explanation:
A z score measures the standard deviation below and above the mean of data. A formula for calculating z-score is
![z=\dfrac{\text{data point}-\text{mean}}{\text{standard deviation}}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B%5Ctext%7Bdata%20point%7D-%5Ctext%7Bmean%7D%7D%7B%5Ctext%7Bstandard%20deviation%7D%7D)
Essential facts about z-scores:
If data is above average, then the z-score is positive.
If data is below average, then the z-score is negative.
if the point is close to average, then z-score is close to 0
if the point is above 333 or blows 3 then z score is unusual.
As the probability of X less than or equal to 23.6474819 and the probability of X is less than or equal to -0.1909414, as the points are less than the condition, then there are unusual and equal to the unusual situation.
