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

During a recent 30-day period, the Squish restaurant sold 600 Ocean Delights at a price of $6.45. During the next 30-day period,
GREYUIT [131]

Answer:

-4.3; inelastic

Explanation:

Initial price = $6.45

Initial quantity demanded = 600

New price = $6.95

New quantity demanded = 400

Percentage change in Quantity demanded:

= (Change in quantity demanded ÷ Initial quantity demanded) × 100

= [(400 - 600) ÷ 600] × 100

= (-200 ÷ 600) × 100

= 0.3333 × 100

= -33.33%

Percentage change in price:

= (Change in price ÷ Initial price) × 100

= [($6.95 - $6.45) ÷ $6.45] × 100

= ($0.5 ÷ $6.45) × 100

= 0.0775 × 100

= 7.75%

Therefore, the price elasticity of demand is as follows:

= Percentage change in quantity demanded ÷ Percentage change in price

= -33.33 ÷ 7.75

= -4.3

Hence, the price elasticity of demand is inelastic.

Schach [20]

Answer:

3,825.2 labor hours

Explanation:

Learning rate (Unit 1 and unit 2):

= Labor hour required for 2nd unit ÷ Labor hour required for 1st unit

= 1,200 ÷ 2,000

= 0.60

Learning rate (Unit 2 and unit 3):

= Labor hour required for 3rd unit ÷ Labor hour required for 2nd unit

= 1,130 ÷ 1,200

= 0.94

Average of learning rates = (0.60 + 0.94 ) ÷ 2

                                           = 0.77

As per learning curve calculator the value of 77% for 6 units = 4.0776

Cumulative time = Factor × Time of first unit

                           = 4.0776 × 2,000

                           = 8,155.2

Hence,

Time for next three units:

= Cumulative time - Sum of the time of first, second and third unit

= 8,155.2 - (2,000 + 1,200 + 1,130)

= 3,825.2 labor hours should Simpson plan for.

netineya [11]

Answer:

a) $12,500 unfavorable

b) 0

Explanation:

variable factory overhead controllable variance = actual variable overhead expense - (standard variable overhead per unit x standard number of units)

actual variable overhead expense = $725,000

standard variable overhead per unit = $712,500 / 60,000 = $11.875

standard number of units = 60,000

variable factory overhead controllable variance = $725,000 - $712,500 = $12,500 unfavorable

Controllable factory overhead is not related to any changes in the actual volume or quantity produced.

Fixed factory overhead volume variance = actual fixed overhead - standard fixed overhead = $262,500 - $262,500 = 0

Fixed overhead was exactly the same as the standard or budgeted overhead.
