Donatello co. has identified an activity cost pool to which it has allocated estimated overhead of $9,600,000. it has determined the expected use of cost drivers for that activity to be 800,000 inspections. widgets require 200,000 inspections, gadgets 150,000 inspections, and targets 450,000 inspections. how much is the overhead assigned to each product? a) widgets $2,400,000, gadgets $1,800,000, targets $5,400,000 b) widgets $200,000, gadgets $150,000, targets $450,000 c) widgets $3,200,000, gadgets $3,200,000, targets $3,200,000 d) widgets $3,200,000, gadgets $1,600,000, targets $4,800,000

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
