Explanation:
a) The distribution should be right skewed as most of the numbers lies at that side while using the median to correctly represent an observation in the distribution.
To represent the variability of the observations, interquartile range could be used. Since, there is a good number of expensive houses and this would increase the mean and standard deviation. So, it is better to use interquartile range to represent it, i.e. upper quartile for expensive houses, and lower quartile for less expensive houses and middle quartile for mid-range priced houses.

Solution :
The optimal order quantity, EOQ = 
EOQ = 
= 115.47
The expected number of orders = 

= 17.32
The daily demand = demand / number of working days

= 8.33
The time between the orders = EOQ / daily demand

= 13.86 days
ROP = ( Daily demand x lead time ) + safety stock

= 76.64
The annual holding cost = 

= 207.85
The annual ordering cost = 

= 207.85
So the total inventory cost = annual holding cost + annual ordering cost
= 207.85 + 207.85
= 415.7
