1.In log-scale, the apparent distance between 1 and 100 is same as the distance between 50 and

a)0.5

b)500

c)50000

2.You are using the Kernel Density Estimation method with a rectangular kernel to estimate the underlying distribution of your data (X = [5, 1, 3, 1, 2, 3, 5, 5, 6, 5]). The width of the rectangular kernel is 1.2. If we examine the resulting distribution, what would be the area under the distribution/curve (or the estimated probability mass) that is within the range [0, 4]?
