Answer:
test statistic, z = −1.74
Step-by-step explanation:
given data
students n = 100
mean time x = 41.13 seconds
σ = 5
we consider µ = 42
solution
we get here The test statistic that is express as
test statistic, z = 
......................1
put here value and we will get
test statistic, z = \frac{41.13-42}{\frac{5 }{\sqrt{100}}}
test statistic, z = −1.74

Answer:
The formula for the volume of a cone is 1/3 Bh. This means 1/3 the Area of the base times the height. You can calculate the area by multiply length and width. Area is two-dimensional. Multiplying height by it adds another dimension. When writing area, we say units squared. When writing volume, we say units cubed, because it is three dimensional.
