A researcher measures the heights in meters of a rare plant species in a sample of 1010 specimens. The sample mean is 1.821.82 meters, with a sample standard deviation of 0.210.21 meters. Construct a 99%99\% confidence interval for the population mean height, assuming the heights are normally distributed.

(1.60 m,2.04 m)(1.60 \text{ m}, 2.04 \text{ m})

(1.45 m,2.19 m)(1.45\text{ m},2.19\text{ m})

(1.70 m,1.94 m)(1.70\text{ m},1.94\text{ m})

(1.50 m,2.14 m)(1.50\text{ m},2.14\text{ m})
