Answer:

n=(\frac{2.262(3)}{0.25})^2 =736.79 \approx 737

So the answer for this case would be n=737 rounded up to the nearest integer

Step-by-step explanation:

We have the following info given:

\bar X = 12 the sample mean

s = 3 the sample deviation

n = 10 represent the sample size

The degrees of freedom are given by:

df =n-1 =10-1=9

The margin of error is given by this formula:

ME=t_{\alpha/2}\frac{s}{\sqrt{n}}    (a)

And on this case we have that ME =0.25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

n=(\frac{t_{\alpha/2} s}{ME})^2   (5)

The confidence level is 95% and the critical value for this case would be given by t_{\alpha/2}=2.262, replacing into formula (5) we got:

n=(\frac{2.262(3)}{0.25})^2 =736.79 \approx 737

So the answer for this case would be n=737 rounded up to the nearest integer

What two ways can you find the product of 8x997 using mental math
ss7ja [257]
8=10-2 or
997=1000-3
so we can use distributive property
remember, a(b+c)=ab+ac

for the first one
8(997)=(10-2)(997)=997(10-2)=997(10)+997(-2)=9970-1994=7976

2nd one
8(997)=8(1000-3)=8(1000)+8(-3)=8000-24=7976
