Histogram of x 0.6 0.5 0.4 0.3 Density 0.2 0.1 0.0 0 2 6 8 10 12 X (a) Calculate (approximately) the proportion of sampled observations between 0.1 and 0.8. (b) If the sample size were n = 620, calculate (approximately) the number of obser vations larger than 1.5. (c) Define the mode as the midpoint of the category containing the largest proportion of observations. Calculate the mode for this histogram
