Using R Studio

I have two data sets created See below. I want to use that to complete these tasks. My data sets are totalrain (per year over 11 year timeframe) and avgtemp (avg temp per year over 11 year timeframe)

How do I plot these two variables against time. Superimpose the mean of all 11 years over the plot as horizontal brown line. Use an appropriate plot to show and verify whether the 11 values are possibly from a normal distribution. Write a function that accepts a array of values and returns a array of z_scores. Use the function to display z_scores of the 11 values

totalrain = c(131.2,128.0,130.7,190.6,263.4,138.0,207.3,161.5,78.8,166.5,170.9)

avgtemp = c(8.6,8.7,6.9,7.1,7.1,7.7,6.9,7.3,9.8,8.8,7
