Indirect material cost: y
explained by units produced: x
Linear regression. Cost estimation equation: y=mx+b
Constant: b=$15,640
Standard error of y estimate=$3,600
r^2=0.7704
Number of observations: n=22
x coeffient: m=11.25
Standard error of x coefficient=2.19
m=11.25, b=15,640 → y=11.25x+15,640
Answer: The cost estimation equation is y=11.25x+15,640
Answer:
third graph
Step-by-step explanation:
We represent the above information in a two way frequency table.
Have Snowboarded Never Snawboarded Total
Skateboard 35 64 99
No Skateboard 13 147 160
Total 48 211 259
Therefore, the third graph is the correct answer.
