A is the right answer ( I say) because 1 over 4 if you times it with 2 you get 1 over 8
Your welcome I hope this works for u
Answer: A
Step-by-step explanation:
Xyz = 45
To find xz divide both sides by y:-
xz = 45/y
Answer:
Correct formula for a 99% confidence interval for the population mean =
Step-by-step explanation:
We are provided a simple random sample of 144 items of which sample mean, xbar = 1250.25 and Standard Deviation, s = 480.
We know that
follows
i.e.;
follows ![t_1_4_3](https://tex.z-dn.net/?f=t_1_4_3)
So, 99% confidence interval is given by ;
P(-2.61138 <
< 2.61138) = 0.99 {because at 143 degree of freedom t table
gives critical value of 2.61138 at 0.5% level}
Now, after further solving this we get,
99% confidence interval for the population mean =
Since, in the question options are not given so this must be the correct formula for calculating 99% confidence interval for the population mean.
