Answer:

a. H0 : U ≥ 15

   Ha : U < 15

b. Type I error is incorrectly conclude that the pain is reduced in less than 15 minutes.

c. Type II error is fail to conclude that time for pain reduction is less than 15 mints when actually its less than 15 minutes.

Explanation:

Null hypothesis is a statement that is to be tested against the alternative hypothesis and then decision is taken whether to accept or reject the null hypothesis.

Type I error is one in which we reject a true null hypothesis.

Type II error is one in which we fail to reject the null hypothesis that is actually false.

HACTEHA [7]

Answer:

$175,808

Explanation:

P=R (1-(1+i)^-n)/i

Where P=780,000*90%=$702,000

R=?

i=8%

N=5 years

By putting above values in formula, we get

P=R(1-(1+.08)^-5)/.08

702,000=R*3.993

R=702,000/3.993

R=$175,808

Job A3B was ordered by a customer on September 25. During the month of September, Jaycee Corporation requisitioned $1,500 of dir
Dmitriy789 [7]

Answer:

The answer is: $29,000

Explanation:

To calculate Job A3B's costs during September we must add direct materials plus 3 times direct labor:

September costs = direct materials + (direct labor x 3) = $1,500 + $9,000

September costs = $10,500

We do the same for October:

October costs: direct materials + (direct labor x 3) = $2,000 + $16,500

October costs = $18,500

The total cost for Job A3B is: $10,500 + $18,500 = $29,000

Preparing a Cost of Goods Sold Budget
Art [367]

Answer:

Direct Materials      $    14*20,000            = $ 28000

Direct Labor            $  14*1.9* 20,000       = $ 532,000

Variable Overhead  $ 14*1.9*1.2*20,000  = $ 638400

Fixed Overhead $ 14*1.9*1.8*20,000  =  $957600

Total Manufacturing Cost $                = 2156000

Less: Ending Inventory $   107.8*730 = 78649

Cost of Goods Sold                      $2077306

Working:

Total Manufacturing Cost $  per unit      = 2156000/ 20,000= 107.8 $

Ending Inventory $   107.8*730 = 78649
