Either the question should be rephrased or the code should be changed - it asks about days above 0 degrees but the answer includes temps at 0 degrees. There are 218 days at or above but only 159 above.

  1. How many data points are from days where the maximum ground temperature got above 0 degrees Celsius? What percent/proportion do these represent? Use: filter() and nrow() group_by() and summarize() or sum()

    How many data points are from days where the maximum ground temperature got above 0 degrees Celsius?

    nrow(mars %>% filter(max_ground_temp >= 0))

    [1] 218
