Answer the questions below. For each part, show yourcalculations and/or explain briefly how you arrived at your answer,as appropriate or needed.
Required:
- Convert the frequency distribution above into a probabilitydistribution (or relative frequency distribution) showing theproportion of days (rather than the number ofdays) that the number of televisions sold was 0, 1, 2, 3, 4, and 5respectively. ( 3 marks)
- Compute the mean of this general discrete probabilitydistribution. ( 3 marks)
- Compute the standard deviation of this general discreteprobability distribution. ( 5 marks)
- What is the probability that exactly 4 televisions will be soldon any given day? What is the probability that 2 or moretelevisions will be sold on any given day? What is the probabilitythat less than 2 televisions will be sold on any given day? What isthe probability that between 1 and 4 televisions inclusive will besold on any given day? (4 mark)
