Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 66​
Katen [24]

Answer:

There is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance

Step-by-step explanation:

H0: sigma= 66%

Ha:sigma < 66%

Chi square =(28-1)*2.82^2/66^2=0.049

p value =0.286

as p value>0.01 we do not can reject H0

So there is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance

A DEF is a right triangle.
Sergeeva-Olga [200]

Answer:

The statement is false because ΔDEF is not a right triangle.

Step-by-step explanation:

We can figure out if this triangle is a right triangle by using the Pythagorean Theorem. The Pythagorean Theorem is <em>a² + b² = c².</em>

<em>a = 26</em>

<em>b = 27</em>

<em>c = 48</em>

Now, let's plug these numbers into the formula.

(26)² + (27)² = (48)²

676 + 729 = 2304

1405 = 2304

1405 does not equal to 2304.

So, ΔDEF is not a right triangle.
