You are part of a research team dedicated to understanding the impact of climate change on lavender oil production in commercial plantations. Your research question is: does daily maximum temperature have an effect on the amount of lavender oil in lavender leaves? To answer your question, you conduct a linear regression between daily maximum temperature and the amount of lavender oil in lavender leaves (micrograms).
Using least squares regression (in R) with a sample size of 45 data points, you estimate the slope of the relationship to be 1.31. The standard error of the slope is 0.509. What is the p-value for the null hypothesis that there is no effect of maximum daily temperature on lavender oil production?
