Answer:
m∠Z1 = 93°
Step-by-step explanation:
Vertical Angles are the angles opposite each other when two lines cross.
They are congruent (the same as each other).
Therefore, m∠Z1 = m∠Z2, so if m∠Z2 = 93° then m∠Z1 = 93°
Complete question :
A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.
Construct a confidence interval for the mean jump height of gray kangaroos.
Answer:
(271, 301)
Step-by-step explanation:
Given that:
Mean (x¯) = 286
Margin of Error = 15 inches
The confidence interval :
(Mean - Margin of Error), (mean + margin of error)
(286 - 15), (286 + 15)
(271, 301)
Hence confidence interval equals : (271, 301)
