Answer the questions based on the data and output given. Please read carefully and help to answer if you're an expert in Statistics (SPSS Software)

An experiment was carried out to investigate variation of solubility of chemical Y in a water. The quantities in kilograms that dissolved in 1 litre of water at nine different temperature levels was recorded and data has been analysed using IBM-SPSS software. Temperature (C) 10 15 20 25 30 35 40 50 70 Mass (kg) 1.6 2.2 2.4 2.7 3.5 4.0 5.1 7.0 8.3 Table 1: Correlations Temperature Mass Temperature Pearson Correlation 984" Sig.

Hence, comment on the value. 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 100 C. V) Identify whether the prediction value in (iv) is valid or not. Justify your answer using a reasonable reason
