1. In R Studio create a plot with two subplots (2 rows, 1 column):

a). Display five Gaussian pdf curves for the six mean/standard deviation pairs (0, 1), (0, 2), (0, 3), (1, 1), (1, 2), (1.3) in the upper subplot using distinct colors for each curve.
b). Repeat the same procedure for corresponding cdfs in the lower plot.

Code snippet:

mean = c(0,0,0,1,1,1)
sd = c(1,2,3,1,2,3)
x = seq(-4,4,length=200) #input data
hx = dnorm(x, mean = 0, sd = 1)
colors <- c("black", "red", "green", "blue", "lightblue","purple")

labels <- c("(0,1)", "(0,2)", "(0,3)", "(1,1)", "(1,2)","(1,3)")

par(mfrow=c(2,1))  #for subplotting

plot(x, hx, type="l", main="pdf curves")

for(i in 2:length(mean)){
lines(x, dnorm(x, mean = mean[i], sd = sd[i]), lwd=2, col=colors[i])
  }

legend("topright", title="pdf distributions",
labels, ncol = 2,fill = 1:6, col=color ,cex = 0.45)

hx1 = pnorm(x, mean = 0, sd = 1)
plot(x, hx1, type="l", xlab="x value",
ylab="Density", main="cdf curves", lty = 1)
for(i in 2:length(mean)){
lines(x, pnorm(x, mean = mean[i], sd = sd[i]), lwd=2, col=colors[i])
  }
legend("topleft", title="cdf distributions",
labels,fill = 1:6, ncol = 2, col=colors,cex = 0.45)

Use R-Studio to plot this PAIRED SAMPLES T-TEST To motivate citizens to conserve gasoline, the government is considering mounting a nationwide conservation campaign. However, before doing so on a national level, it decides to conduct an experiment to evaluate the effectiveness of the campaign. For the experiment, the conservation campaign is conducted in a small but representative geographical area. Twelve families are randomly selected from the area, and the amount of gasoline they use is monitored for 1 month before...
