Answer:

Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.

Explanation:

A confidence interval is a range of values, derived from the sample statistics, which may include the value of an unknown population parameter.

A 95% confidence interval indicates that between 152 of 160 samples (95%) of the same population will produce confidence intervals that will contain the population parameter.

It also means that we have a 95% confidence that the average (average amount) is among the resulting amounts obtained.

Logically, option "D" is missing the final part. This would be: D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $ 15.

This is the only true option, since the test is based on a sample of only 160 households, the entire population of households cannot be included.

Hence, the correct option is:

Option D. We are 95% confident that the mean amount spent on electric service among the 160 households is between $151 and $216.

Explanation:

A. Calculation to determine the amount of net income that Lauhl should recognize in April under cash-basis accounting

Cash-basis accounting

=$24,000 -$5000-$3,400

Cash-basis accounting =$15,600

Therefore the amount of net income that Lauhl should recognize in April under cash-basis accounting is $15,600

B. Calculation to determine the amount of net income that Lauhl should recognize in April under the accrual-basis Accounting

Accrual-basis Accounting=($24,000/6) -$1300 + $2500 - $3,400 - $850

Accrual-basis Accounting=$4,000-$1,300+$2,500+$3,400-$850

Accrual-basis Accounting=$7,750

Therefore the amount of net income that Lauhl should recognize in April under the accrual-basis Accounting is $7,750

Direct Materials, Direct Labor, and Factory Overhead Cost Variance Analysis
seropon [69]

Answer:

Instructions are listed below.

Explanation:

Giving the following information:

Mackinaw Inc. processes a base chemical into plastic. Standard costs and actual costs for direct materials, direct labor, and factory overhead incurred for the manufacture of 40,000 units of product were as follows:

Standard Costs - Actual Costs

Direct materials 120,000 lb. at $3.20 118,500 lb. at $3.25

Direct labor 12,000 hrs. at $24.40 11,700 hrs. at $25.00

Factory overhead Rates per direct labor hr., based on 100% of normal capacity of 15,000 direct labor hrs.:

Variable cost, $8.00 $91,200 variable cost

Fixed cost, $10.00 $150,000 fixed cost

Each unit requires 0.3 hour of direct labor.

A) Direct material price variance= (standard price - actual price)*actual quantity

Direct material price variance= (3.20 - 3.25)*118,500= $5925 unfavorable

Direct material quantity variance= (standard quantity - actual quantity)*standard price

Direct material quantity variance= (120,000 - 118,500)*3.20=-$4,800 favorable

Total direct material variance= 5,925 - 4,800= 1,125 unfavorable

B)Direct labor efficiency variance= (SQ - AQ)*standard rate

Direct labor efficiency variance= (12,000 - 11,700)*24.40= -$7,320 favorable

Direct labor price variance= (SR - AR)*AQ

Direct labor price variance= (24.40 - 25)*11,700= $7,020 unfavorable

Total direct labor variance= $300 favorable

C) Variable factory overhead controllable variance= (8*15,000 - 92,100)= -$27,900 favorable

Fixed factory overhead volume variance= (10*15,000 - 150,000)= 0

Total factory overhead variance= 27,900 favorable
