Answer:
~ 1561.235
Explanation:
Given :
Standard deviation can be determined by the 
Standard deviation=SD
=
σ = 8
Now using the formula
R=1561.235
~ 1561.235
A measure such as direct labor-hours or machine hours used to assign overhead costs to products and services is called a cost driver or an allocation base.
An entity allocates its overhead costs on the basis of an allocation base. An allocation basis is a measurement, such as the amount of square footage occupied, kilowatt hours consumed, or machine hours used.
Cost accounting assigns overhead expenses using an allocation base. An allocation base can be a quantity, such as the amount of machine hours used, kWh spent, or occupied square footage.

Answer:
Total materials variance = (Actual quantity * Actual price) - (Standard quantity * Standard price)
= 2,850 - (230 * 14.4)
= 462 (Favourable)
Materials price variance = (Standard price - Actual price) * Actual quantity
= [1.8 - (2,850/1,500)] * 1,500
= 150 Unfavourable
Materials quantity variance = (Standard quantity - Actual quantity) * Standard price
= [(230 * 8) - 1,500] * 1.8
= 612 Favourable
Total labour variance = (Actual hours * Actual rate) - (Standard hours * Standard rate)
= 19,458 - (230 * 84)
= 138 Unfavourable
Labour price variance = (Standard rate - Actual rate) * Actual hours
= [14 - (19,458/1,410)] * 1,410
= 282 Favourable
Labour quantity variance = (Standard hours - Actual hours) * Standard rate
= [(230 * 6) - 1,410] * 14
= 420 Unfavourable
