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)
Answer:
0.67
Step-by-step explanation:
The total number of spins is
7 + 13 + 20 + 14 + 9 = 63
The numbers of spins that landed on blue, green, and purple are:
13, 20, 9
Total blue, green, purple: 13 + 20 + 9 = 42
Based on the spins that are tabulated, the probability the spinner will land on blue, green, or purple is
42/63 = 2/3 = 0.67
