Compute the right solution of the following question
Question- Here is the summary statistics for the weekly sales (in dollar amounts) of laptop computers at a large computer store: lowest sale = $8,400, mean sale = $40,000, standard deviation = $5,000, median = $30,000, First quartile = $12,000, Third quartile = $45,000, Highest sale = $85,000.
Part 1- Do you think the distribution of weekly sale amounts is symmetric, skewed to the left, or skewed to the right? Explain why.
Part 2- Between what two values are the middle 50% of the weekly sale amounts found?
Part 3- Suppose the computer store decides to run an offer, and each week a randomly selected customer receives a $500 cash prize. Suppose the prize amount is deducted by the store weekly sale. So weekly sales are reduced by $500. Find the new values of the summary statistics.
I want assist to calculate the new values of the summary statistics.
