(10 points) Model Price $10,000 $12,000 $ 8,000 Number 10 12 4. a. The mean of a distribution is 20 and the standard deviation is 2. Use Chebyshev's theorem to find at least what percentage of values will fall between 12 and 28. (10 points) b. A sample of the labor costs per hour to assemble certain product has a mean of $2.60 and a standard deviation $0.20. Using Chebyshev's theorem, find the values in which at least 88.89% of the data will lie. (10 points)

Explanation / Answer

3) weight mean price = 8*10000+10*12000+12*8000/ 8+10+12

= 80000+120000+96000/30

=296000/30

weighted mean = 9866.67
