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

Suppose you deposit $1,200 into a bank account. The account earns yearly simple interest at a rate of 1 3/4%. How many years wil
igor_vitrenko [27]

Answer:

6 years

Step-by-step explanation:

1.75% of 1,200 = 21

so 1 year= 21

21+21= 42         2 years

42+21=63           3 years

63+21=84            4 years

81+21=105             5 years

105+21=126            6 years

Or you can do

21x6=126 so it has to equal 6 years
