There are two Gaussian curves below (Plots A and B), along with the respective R source codes.
Looking at the plots and the source codes provided, identify the parameters of respective
Gaussian
express the areas under the curves in terms of F(x). ( Do not calculate those areas. The answers must be like F(x) or 1-F(x) for a relevant value of x.)
Below is the source code and image for part a
![PLOT-A
X<-seq(-4,8,0.01)
y <-dnorm(x, 2.2, 1.9)
plot(x,y,type = "1")
polygon(c(x[x>0], 0),c(y[x>0],y[x = = -4]),col = "honeydew2")](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdb82eee3-c597-43b7-b98f-cffc18fbca72%2Fb3d7696c-e4b6-4505-98dd-6dea492b5b76%2Fw3zjagd_processed.png&w=3840&q=75)
From the first line of the code we can see that,
x<- seq(-4,8,0.01)
The lower limit of x is -4 and upper limit is 8.
The value of x is between- and 8.
From the second line,
y<- dnorm(x,2.2,1.9)
we know that, y<-dnorm(x,mean,standard deviation)
So, mean= 2.2 and standard deviation = 1.9
