The calculated value of the Z statistic to test the potential buyer's belief at the 1% significant level is -2.57512627.
The calculated Z score is slightly greater than the critical value of -2.575, the potential buyer's view that weekly store revenues are less than $7,000 stands vindicated.
Since store revenues are assumed to be normally distributed and population standard deviation is given, we can use the Z-test. The relevant test statistic is the Z-score.
We use the following formula for calculating the Z score:
Z = (X - μ) / (σ /√n)
Substituting the relevant values we get,
Z = (6400 -7000) / (1042/√20)
Z = -600 / 232.9982833
Z = -2.57512627
C: electronic fuel injection system control the fuel and air flow automatically during ignition. (In fact the most modern system probably completely ignore throttle input during ignition, at least those that are drive by wire rather than mechanical connections)
Answer:
Predetermined rates for each cost pool
Ordering = <u>$120,000</u>
240,000 orders
= $0.50 per order
Machine set-up = <u>$85,000</u>
340,000 set-ups
= $0.25 per set-up
Inspection = <u>$75,000</u>
75,000 inspections
= $1 per inspection
Explanation:
The predetermined rates are obtained by dividing the estimated overhead for each cost pool by the cost driver.
Two importance of office resources are greater output and promote productivity .
<h3>What are office resources ?</h3>
All of the resources and amenities found in an office, <em>including people, tools and supplies, furniture and equipment, cash, modes of</em> <em>transportation, and communication</em>, are referred to as office resources. These resources are used to help the organization achieve its goals.
