Calcium is essential to tree growth. In 1990, the concentration of calcium in precipitation in Chautauqua, New York, was 0.11 milligram per literresults in the following data:0.1260.183 0.1200.234 0.313What are the null and alternative hypotheses?= 11P #Ho μH₁11(Type integers or decimals.

A boxplot does not show any outliers. Does the sample evidence suggest that calcium concentrationshave changed since 1990?
