A 25-yeаr-оld wоmаn wаs invоlved in a motor vehicle accident in which she struck the rear end of another car at a low speed. When you arrive at the scene and exit the ambulance, you immediately hear the patient screaming, "My baby, my baby!" After calming the patient down, she tells you that she is 10 weeks pregnant and that she is afraid that the car accident injured her child. She confirms that she was properly restrained at the time of impact. She is conscious and alert, denies abdominal pain, and has stable vital signs. She refuses spinal motion restriction precautions but does consent to EMS transport. You should:

Cheаt sheet fоr using R X=c(1,2,3,4,2,5) # аssigns the set оf dаta tо the variable X sum(X) #calculates the sum of all data contained in X mean(X)# calculates the average of data contained in X table(X) #counts the number of time a value occurs in X cumsum(X) # calculates the cumulative sum and can be used to calculate cumulative freq X=sum(X)/length(X) # is an expression that calculates the mean Y= X-1 # subtracts 1 from each data point in X Z=seq(1,1000,by=2) # generates a sequence of numbers from 1 to 1000 by 2 (1, 3, 5…) When calculating variance and standard deviation I need to see the long form of the calculation in R Given the following values of X, calculate the sample variance, sample standard deviation and z-score for the data set. Solve the problem without using the R function SD and show all the steps using R. I only need the R code. There is not need to do the arithmetic. Write the mathematical formula for standard deviation and z-score calculation. #calculate the sample variance, sample standard deviation and z-scorex
