Here the null hypothesis h0 is mu not equal to 0 and alternative hypothesis h1 is mu not greater than 0.
00:10
Level of significance alpha is 0 .01, n equal to 8 and degrees of freedom equal to 7.
00:19
At alpha equal to 0 .001 and with degrees of freedom equal to 7, the t value is calculated using except here t value is obtained as 2 .998.
00:45
Reject h -not if t less than or equal to none or t greater than or equal to 2 .998.
01:03
For the calculation, assume that unbranded condition has the first sample.
01:09
Let us denote d equal to u minus a.
01:23
U equal to 36 .1, 55, 51, 51 ,1, 38 .9, 43 .2, 43 .2, 48 .8 .8, 28 .8, 25, 25, 6, and 49 .6.
01:41
A are 28 .5, 20, 46, 34, 36, 52 .5, 26 .5, 46 .5, 46 .5.
01:58
U minus a, values are 7 .6, 26 .5, 22 .6, 10 .4, 14 .7, 20 ,000, 20 .3 .3 .000.
02:13
14 .7.
02:13
Minus 2 .9, 21 .1.
02:21
D equal to 7 .6, 26 .5, 22 .6, 10 .4, 14 .7, 20 .3, minus 2 .9, 21 .1.
02:39
The difference of mean d bar equal to summation d ,i, sorry, addition di divided by, that is equal to 7 .6 plus 26 .5 plus 22 .6 plus 10 .4 plus 14 .7 plus 14 .20 .3 plus 21 .1 minus 2 .9 divided by 8.
03:15
That is equal to 15 .03775.
