Answer:
Step-by-step explanation:
Type I error occurs if the null hypothesis is rejected when in the real sense, it is actually true.
Type II error occurs if the null hypothesis is not rejected when in the real sense, it is actually false.
The null hypothesis is
H0: μ = 9.6 hours
The alternative hypothesis is
Ha: μ > 9.6
Suppose that the results of the sample lead to non rejection of the null hypothesis if in fact the mean running time has increased it means that
a) the conclusion is a type I error because the null hypothesis was of rejected even though it was false

We could invent set B: {-2, 1, 3, 5, 6, 10} and then correctly state tht set A is a subset of B, because {-2, 1, 3} is also found in A.
Answer :
70 square units
Step-by-step explanation:
I have plotted the points on the coordinate system and connected roughly using a red line. Image is attached.
The arrow created, consists of a TRIANGLE and a RECTANGLE. The area of the arrow would be:
Area of Arrow = Area of Triangle + Area of Rectangle
Area of Triangle = 0.5 * base * height
Base is 12 units
Height is 7 units, so
Area of Triangle = 0.5 * 12 * 7 = 42
Now,
Area of Rectangle = length * height
Length is 7
Height is 4
Area of Rectangle = 7 * 4 = 28
Area of Arrow = 42 + 28 = 70 square units
