  1. Std. Err (standard error): The average deviation of sample means from the hypothesized population mean of 4.73 drinks is about 0.44 drinks.
  2. T-stat (T-score): The observed sample mean of 3.93 drinks is 1.8 standard errors below the hypothesized population mean of 4.73 drinks.
  3. P-value: If the population mean is 4.73 drinks, there is a 7.2% chance that sample means will have an error larger than that observed in our sample (observed error = 4.73 – 3.93 = 0.8 drinks) when selecting random samples of 75 students.

Can someone summarize these points
