To find the mean number of new disease cases for the given six days in May 2020, we first need to sum the number of cases for each day, then divide by the number of days.
The cases recorded for the last six days of May are:
- 26-May: 358
- 27-May: 342
- 28-May: 368
- 29-May: 403
- 30-May: 494
- 31-May: 446
First, sum the number of cases:
\( 358 + 342 + 368 + 403 + 494 + 446 = 2411 \)
Next, divide the total number of cases by the number of days (6):
\[ \text{Mean number of cases} = \frac{2411}{6} \]
\[ \text{Mean number of cases} = 401.83 \]
So, the mean number of new disease cases for these six days is approximately 401.83.
The number of new disease cases in a county for the last six days of May in 2020 are recorded as follows. Find the mean number of cases for these days.
26-May : 358
27-May : 342
28-May : 368
29-May : 403
30-May : 494
31-May : 446
