Answer:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:
c). Reject H0 if test statistic is greater than 1.895.
Step-by-step explanation:
The system of hypothesis for this case are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
The degrees of freedom are given by:
The p value for this case can be calculated from this probability:
The critical value for this case can be calculated using the t distribution with 7 degrees of freedom and the critical value would be a value who accumulates 0.1 of the area in the right of the distribution and the best decision based on the possible options would be:

Answer:
(a) $782.00
(b) $218.00
Step-by-step explanation:
(a)_
Total before VAT:
$367.00 + $313.00 = $680.00
15% VAT on $680:
15% of $680.00 = 0.15 × $680 = $102.00
Total after VAT:
$680.00 + $102.00 = $782.00
(b)
$1000.00 - $782.00 = $218.00
