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
there are no pictures of a graph BUT i can give you the intercepts.
x=2
y=12
OR
x=4
y=8
OR (sorry i cant see the graph options its one of the three)
x=8
y=3
its a solid line
x are the shoes
y are the outfits
