How do the number of cups of coffee that nurses drink during their shift differ between the day shift and night shift nurses? The probability distribution for the amount of coffee consumed for the two nursing shifts is provided in the table.
Answer
The distribution of number of cups of coffee for the day shift is , while the distribution for the night shift is . The mean for the distribution of the day shift is the mean for the night shift. By l:
roughly symmetric
The distribution of number of cups of coffee for the day shift is , while the distribution for the night shift is . The mean for the distribution of the day shift is the mean for the night shift. By l:
skewed left
The distribution of number of cups of coffee for the day shift is , while the distribution for the night shift is . The mean for the distribution of the day shift is the mean for the night shift. By l:
less than
