0.234 Calcium is essential to tree growth. In 1990, the concentration of calcium in precipitation in Chautauqua, New York, mg was 0.11 milligram per liter A random sample of 8 precipitation dates in 2018 results in the following data: L 0.065 0.262 = 0.120 What are the null and alternative hypotheses? Ho: P 0.11 H₁: P # 0.11 (Type integers or decimals. Do not round.) Find the test statistic. 0.108 to = (Round to two decimal places as needed.) Points: 0 of 1 0.070 ... A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot does not show any outliers. Does the sample evidence suggest that calcium concentrations have changed since 1990? Use the a = 0.1 level of significance. 0.183 Save 0.313
