A researcher suspects that the distribution of bacteria in drops of water follows a Poisson distribution. For each of 300 drops of water, the number of bacteria was determined. The number of drops containing given numbers of bacteria were as follows:
Assuming these count follow a Poisson Distribution, construct an approximate 95% Confidence interval for the mean number of bacteria in a drop of water.
| Number of bacteria | Number of drops |
| 0 | 175 |
| 1 | 75 |
| 2 | 25 |
| 3 | 12 |
| 4 | 7 |
| 5 | 4 |
| 6 | 2 |
| 7 or more | 0 |
