You can use MS Excel Data Analysis in your problem computations. Data Analysis tables have to be submitted. Consider the data set below, representing the ages and maintenance cost (in thousands of pesos per year) for five similar printing presses. Age : 2 5 9 3 8 Maintenance Cost : 62 130 236 54 220 Draw a scatterplot of this data set. What kind of relationship do you see? Find the correlation between age and maintenance cost. What do you learn about it? Does age explain a significant amount of the variation in maintenance cost? How do you know? Hint: use t-test with 5% level of significance
