# Hypothesis testing for population temperature

In order to monitor the ecological health of the Florida Everglades, various measurements are recorded at different times. The bottom temperatures are recorded at the Garfield Bight station and a mean temperature of 30.4°C is obtained for the temperatures recorded on 61 different days. Assuming that σ = 1.7°C, test the claim that the mean population temperature is greater than 30.0°C. Use a 5% level of significance.

1. State the Null Hypothesis and the Alternative Hypothesis.

2. Determine the test statistic.

3. Determine the P-value.

4. Make a decision regarding the hypotheses based on the P-value and the Level of Significance.
