The company offers free buffet lunch for candidates attending the interview. As a HR analyst, Luke is asked to estimate the amount of salad to order for the interview day. Sampling suggests that the amount of salad taken by each candidate (measured in grams) distributes as the below diagram. What is the distribution as described in the below chart and probability density function of the distribution in the chart? What is the mean and standard deviation of this distribution, respectively? What is the probability of a candidate taking salad between 13 – 16 grams?
