WebJul 17, 2024 · Your calculated t value of 2.36 is far from the expected range of t values under the null hypothesis, and the p value is < 0.01. This means that you would expect to see a t value as large or larger than 2.36 less than 1% of the time if the true relationship between temperature and flowering dates was 0. WebWe can say this is approximately 0.02. That's 0.02 approximately, the T distribution is symmetric, this is going to be approximately 0.02. Our P-value, which is going to be the …
