The average score of the student in the class at a 99% confidence lies between 1.252 and 3.028

Explanation:

Given values are

n = 14   = 2.14     σ = 1.29  z value for 99% confidence = 2.576

The mean is known one

= (z σ/√14)

=  (2.576 ×1.29÷√14)

(2.576 ×1.29÷√14)

= 2.576 × 0.345

= 0.888

 =  mean- 0.888 = 2.14  - 0.888 = 1.252

 =  mean+0.888 =  2.14 + 0.888 = 3.028

The average score of the students in the class at a 99% confidence lies between 1.252 and 3.028

What will the elasticity of resource demand be if unit wages rise by 5 percent and the number of employed workers falls by 12 pe
Amiraneli [1.4K]

The correct answer is 2.4.

The simplest way to define elasticity of demand is by using the following formula:

Elasticity of Demand = Change in Demand / Change in Prices

Then, in our question we have:

Demand Elasticity = 12% / 5% = 2.4

Why is it called elasticity of demand?

An elastic product is one in which demand significantly shifts in reaction to price fluctuations. In other words, the product's demand point has expanded significantly from its earlier point. It is inelastic if the amount purchased fluctuates little when the price of the good or service changes.

What Does elasticity of demand tells us?

It reveals how much the quantity needed alters in response to pricing changes made by the company. The price elasticity of demand explains how the amount sought in the market changes when the price changes if we are evaluating a market demand curve.

A turret lathe section has eight machines, all devoted to the production of the same part. The section operates 10 shifts/wk. Th
kodGreya [7K]

Answer:

Pc = 8294.4 units per week

Explanation:

Pc = U * A * ( N * sw * Hsh * Rp )/ n

Where

Pc = production capacity in terms of availability and utilization per week

U = utilization factor = 80% = 0.8

A = availability = 90% = 0.9

N = number of work centers = 8

sw = number of shifts per week = 10

Hsh = number of hrs per shift = 8

Rp = hourly production rate = 18 units /hr

n = number of distinct operations = 1 , same machine & part

So therefore,

Pc = 0.8 * 0.9 (8 * 10 * 8 * 18)/ 1

Pc = 8294.4 units per week
