Answer: 2.28 %
Step-by-step explanation:
Given : Mean : ![\mu=\ 48](https://tex.z-dn.net/?f=%5Cmu%3D%5C%2048)
Standard deviation :![\sigma= 12](https://tex.z-dn.net/?f=%5Csigma%3D%2012)
The formula to calculate the z-score :-
![z=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
For x = 72
![z=\dfrac{72-48}{12}=2](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B72-48%7D%7B12%7D%3D2)
The p-value = ![P(2](https://tex.z-dn.net/?f=P%282%3Cz%29%3D1-P%28z%3C2%29)
![1-0.9772498=0.0227502\approx0.0228](https://tex.z-dn.net/?f=1-0.9772498%3D0.0227502%5Capprox0.0228)
In percent, ![0.0228\times100=2.28\%](https://tex.z-dn.net/?f=0.0228%5Ctimes100%3D2.28%5C%25)
Hence, the percentage of pediatricians work more than 72 h per week = 2.28 %
Answer:
False ,false,true, true and true
Step-by-step explanation:
The general form of the linear equation is:
y = mx + c where:
m is the slope and c is the y intercept
We are given that the slope is equal to -2
Therefore, the equation now becomes:
y = -2x + c
To get the value of the c, we will use the given point (0,0) to substitute in the equation and solve for c as follows:
y = -2x + c
0 = -2(0) + c
c = 0
Based on the above calculations, the equation of the line would be:
y = -2x
