How can you solve this step by step?<br> 812 divided by 12?

makkiz [27]

Answer:

How I answered this was

Line up 812 divided by 12

So 81 divided by 12 = 72

Subtract 81 - 72

Which would equal 9

then bring down the two in 812

Which would make it 92

Then divide that by 12

which would equal 84

the subtract 92 - 84

that would equal 8

put a decimal then bring down a 0

that would be 80 then divide 80 by 12

that would be 7 which would equal 8 again

so our answer would be 67.6 continuous.

Answer:

a) Sample correlation coefficient, r = 0.7411

bi) test statistic, t = 4.102

bii) P-value = 0.000736

Step-by-step explanation:

a) The formula for the sample correlation coefficient is given by the formula:

$r = \frac{S_{xy} }{\sqrt{S_{xx} S_{yy} }} }$

$S_{xx} = 2,648,130.357\\S_{yy} = 36.7376,\\S_{xy} = 7408.225$

$r = \frac{7408.225}{\sqrt{2648130.357*36.7376} }$

r = 0.7511

i) formula for the test statistic is given by the formula:

$t = \frac{r\sqrt{n-1} }{\sqrt{1 - r^{2} } }$

sample size, n = 4

$t = \frac{0.7511\sqrt{14-1} }{\sqrt{1 - 0.7511^{2} } }$

t = 4.102

ii) Degree of freedom, df = n -2

df = 14 -2

df = 12

The P-value is calculate from the degree of freedom and the test statistic using excel

P-value =(=TDIST(t,df,tail))

P-value = (=TDIST(4.1,12,1)

P-value = 0.000736
