To find the mean number of new disease cases for the last six days of May, follow these steps:
1. Add up the number of cases for each day:
\[ 347 + 341 + 389 + 403 + 475 + 428 \]
2. Calculate the sum:
\[ 347 + 341 = 688 \]
\[ 688 + 389 = 1077 \]
\[ 1077 + 403 = 1480 \]
\[ 1480 + 475 = 1955 \]
\[ 1955 + 428 = 2383 \]
3. Divide the total sum by the number of days (which is 6):
\[ \frac{2383}{6} \approx 397.1667 \]
4. Round the result to the nearest whole number:
\[ 397.1667 \approx 397 \]
So, the mean number of cases for these days is 397.
