26.22 is Rational because it can be written as a ratio of two integers.
Answer: It is true that required total sample size is less than the pilot sample already taken.
Step-by-step explanation:
Since we have given that
N = 30
Margin of error = E = 30
Standard deviation = 60
At 95% level of significance,
z = 1.96
So, the value of sample would be

So, it is true that required total sample size is less than the pilot sample already taken.
Answer:
vw= 22
Step-by-step explanation:
To find the dot product of vw, multiply the corresponding numbers and add them.
v= <3, -8, -3> w= <-4, -2, -6>
vw= (3*-4)+(-8*-2)+(-3*-6)
vw= -12+16+18
vw= 4+18
vw= 22
Based on your question where the quarterly returns for a group of 79 mutual funds with a mean of 1.1% and the standard deviation of 4.5% can be modeled by a normal model so based on that data the possible answer among the choices is B.
Hi,
This is using 'n', so there would be a lot of possibilities, but I would form a circle with the group of people, then each person would shake the person to their right, and then to their right, one time. This method would not vary because a circle can contain even or odd number of people.
Hope this helps!
