One-sample t-test: Check NEON data set you downloaded before, and find one continuous variable. Calculate the sample size, mean y-bar, and standard deviation of the variable. Assume that a population mean µ=y-bar*1.2. Please test whether the sample is drawn from that population. Suppose this is one dataset your downloaded for plant nitrogen content in the plant under warming conditions: 1.5, 2.5, 2.1, 1.8, 2.5, 1.9, 2.0, 1.8, 2.2, 1.9 (g/kg). Please test whether the warming alters nitrogen content in plant compared to normal conditions (µ0=2.4 g/kg).
