On June 1st, 2020, the distribution of new Covid-19 cases by county had a mean of 7.29 and a standard deviation of 110.87. A dedicated but naive CDC analyst decides to model this data using a normal distribution. In other words, letting X be the number of new Covid-19 cases in a county, our analyst models the county-level new case counts as X ~ Normal(7.29, 110.87).
For the following questions, pretend you are the CDC analyst, modeling new case counts as Normal(7.29, 110.87)

Question: What is the R code you would use to calculate the probability that another county had more cases than Orange County (178 cases) without using the Z-score?
Group of answer choices
A) 1-pnorm(q=178, mean=7.29, sd=110.87)
