An experiment was conducted to investigate the variation of chemical Y solubility in water. The amounts in kilograms that dissolved in one liter of water at nine different temperatures were recorded, and the data was analyzed with IBM-SPSS software. Based on the data and IBM-SPSS software output given (refer images): i) Validate that the Pearson correlation coefficient value is 0.984 ii) Compute the value of X in Table 2 iii) Determine the proportion of variance in the dependent variable iv) Estimate mass that dissolved in the water if the temperature is set at 100C.
