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
Can't solve this, because it's not an equation. It's an expression, and I think your goal is to simplify it.
<span>r^2/2r^3 would be better written as
</span><span> r^2 r^2
------- = ----------- this should be reduced by cancelling "r^2:"
2r^3 2r(r^2)
1
-------- (answer)
2r</span>
I believe the answer is D. let me know if im wrong
