QUESTION: Summarize the variable outcome_handwash using the appropriate measures of central tendency and spread. Calculate the standard error of the mean, construct a 95% confidence interval for the mean and interpret these two uncertainty measures (standard error and confidence interval). For the uncertainty calculations, rely on your own calculations (you can use R for these) and also present the formulas you used.

** I have already run the R code, therefore I need help regarding interpretation, uncertainty , formulas etc...

Results are as follow:

summary(cv$outcome_handwash)

Min. 1st Qu.MedianMean 3rd Qu.Max.

> ee = sd(cv$outcome_handwash)/sqrt(nrow(cv))

> print(paste("upper limit: ",round(mean(cv$outcome_handwash)+(z.005*ee),4),"lower limit: ",round(mean(cv$outcome_handwash)-(z.005*ee),4)))
