As a sample of 29 plants was taken in the mean height was 19 cm. A 95% confidence interval for the true mean height of plants of the particular species is (15.8cm, 22.2cm). For students get the following interpretations of the confidence interval. Which of the following is correct? 1. The probability is 0.95 that the mean height lies in the interval (15.8, 22.2). 2. We are 95% confident that the true mean height is 19cm since that value lies in the confidence interval. 3. We can be fairly confident that 95% of all plants of that species have a height between 15.8 cm and 22.2cm. 4. None of the above
