Concept explainers
The table shows the number of people per day who died from SARS in Singapore at two-week intervals beginning on March 1, 2003.
Date | Deaths per day |
March 1 | 0.0079 |
March 15 | 0.0638 |
March 29 | 0.1944 |
April 12 | 0.4435 |
April 26 | 0.5620 |
May 10 | 0.4630 |
May 24 | 0.2897 |
(a) By using an argument similar to that in Example 4, estimate the number of people who died of SARS in Singapore between March 1 and May 24, 2003, using both left endpoints and right endpoints.
(b) How would you interpret the number of SARS deaths as an area under a curve?
