5. An urban sociologist interested neighborliness collected data for a sample of 10 randomly selected adults on \( (X) \) how many years they have lived in the neighborhood and \( (Y) \) how many of their neighbors they regard as friends. Determine whether there is a significant relationship between the two variables. \begin{tabular}{|l|l|l|l|l|l|l|l|l|l|l|} \hline \( \mathrm{X} \) & 1 & 5 & 6 & 1 & 8 & 2 & 5 & 9 & 4 & 2 \\ \hline \( \mathrm{Y} \) & 1 & 4 & 2 & 3 & 5 & 1 & 2 & 6 & 7 & 0 \\ \hline \end{tabular}

A sample of seven households from a moderate-to-high income neighborhood was taken and information on their incomes and food expenditures for the past month were collected. The information obtained is given in table below. Income (RM '00) | Food Expenditure (RM '00) 35 | 9 49 | 15 21 | 7 39 | 11 15 | 5 28 | 8 25 | 9 a) State the independent and dependent variable. b) Draw a scatter plot for the above data. c) Calculate correlation coefficient, r. d) Describe the relationship between the two variables based on the correlation coefficient value. e) Calculate the least square regression line equation, ŷ = b₀ + b₁x . f) Predict the food expenditure for this household when the monthly income is 30.
