Answer:

680 oranges

15 levels

Step-by-step explanation:

Add 2, add 3, add 4, add 5.....

1+3+6+10+15+21+28+36+45+55+66+78+91+105+120=680

15 levels

He can’t add a 16th level, because it would have 136 oranges, which would put him over 800.

In a random sample of 257 adult Orcas in the wild, there were 159 whose total body length was 28 feet or longer. Create a 98% co
REY [17]

Answer:

98% Confidence interval:  (0.5483,0.6891)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 257

Number of adults total body length was 28 feet or longer, x = 159

\hat{p} = \dfrac{x}{n} = \dfrac{159}{257} = 0.6187

98% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.02} = 2.326

Putting the values, we get:

0.6187\pm 2.326(\sqrt{\dfrac{0.6187(1-0.6187)}{257}})\\\\ = 0.6187\pm 0.0704\\\\=(0.5483,0.6891)

is the required 98% confidence interval.
