Answer:

Option (d).

Step-by-step explanation:

Given that,

The area of a Football field is 57,600 sqft

The dimensions of Basketball court is 84ft x 50ft

We need to find what fraction of the football crowd would fit on the court. Taking ratio of the area of basket ball court to the football court as follows :

$R=\dfrac{84\times 50}{57,600}\\\\R=\dfrac{7}{96}\ =\ 0.0729$

It is less than a tenth. Hence, the correct option is (d).

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)
