Answer:

lower range 33.822 years

upper range 38.178 years

Explanation:

step 1:

48 -1 = 47

step 2:

(1 - 95%) / 2 = 0.025

step 3:

we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117

step 4:

divide sample standard deviation by square root of sample size

7.5 years / √48 = 7.5 / 6.9282 = 1.0825

step 5:

multiply results from step 3 and 4

2.0117 x 1.0825 = 2.178

step 6:

for the lower range, subtract step 5 from sample mean

36 - 2.178 = 33.822

step 7: for the upper range, add step 5 with sample mean

36 + 2.178 = 38.178

Calculate ending inventory and cost of goods sold for 2015, assuming the company uses specific identification. Actual sales by t
Zielflug [23.3K]

Answer:

The value of closing inventory is $3,500

Cost of goods sold $40,670

Explanation:

The two tasks here is to compute the value of closing inventory and the costs of goods sold during the year.

The fact that all opening inventory units were sold and that 230 units out of 250 units bought on May 5 leaves 20 units of that batch inventory in closing inventory.

Also, 20 units of 200 units bought on November 3 in inventory since 180 units were already sold.

Hence the value of closing inventory is computed thus:

May 5 20*$85=$1,700

Nov 3 20*$90=$1,800

Total               $3,500

The costs of goods sold are is computed thus:

Opening inventory 60*$82 $4,920

May 5 230*$85                 $19,550  

Nov 3 180*$90                  $ 16,200  

Total                                   $40,670
