Please write down how to type in R studio.

For the problems below, you will only use R to answer and the commands or slight variations given in the assistance on page 1. You will need to copy and paste the commands and output for each part of each problem. USE THE NON-STANDARD NORMAL COMMANDS FOR MORE ACCU- RATE RESULTS AND THE ANSWERS HERE SHOULD BE SIMILAR TO THOSE YOU DID BY HAND BUT NOT PERFECT AS R DOES NOT ROUND LIKE YOU DID! 1. (12.5 points) For another subject in a study, acetone levels were normally distributed with a mean of 870 and a standard deviation of 211 ppb. Find the probability on a given day a subject's acetone level is: (a) between 600 and 1000 ppb (b) over 900 ppb (c) under 500 ppb (d) between 900 and 1100 ppb (e) What is the 15.39th percentile of this distribution? 2. [20 points) In an agricultural experiment, a large uniform eld was planted with a single variety of wheat. The eld was divided into many plots (each plot being 7x100 ft) and the yield (lb) of grain was measured for each plot. These plot yields followed approximately a normal distribution with mean 88 lb and standard deviation 7 lb. What percentage of the plot yields were: (a) 80 lb or more? (b) 90 lb or more? (c) 75 lb or less? (d) between 75 and 90 lb? (e) between 90 and 100 lb? (f) between 75 and 80 lb? (g) Using the information in the problem, nd the yield that would represent the 65th percentile? (h) Using the information in the problem, nd the yield that would represent the 35th percentile
