Answer:
Explanation:
For example: Suppose you want to check the average working hour of employees. You may think that the average duration of an employees is 7.6 hours. You want to check this claim so you collect a sample of 20 employees and note their duration of work. (please check attached file for this, and continue)
NULL HYPOTHESIS H0:u= 7.6 HOURS
ALTERNATIVE HYPOTHESIS Ha: ≠7.6 HOURS
alpha=0.05
t= 7.765-7.6/1.25/sqrt(20)
t= 0.165/1.25/4.47
t= 0.165/0.28
t= 0.589
degrees of freedom= n-1=20-1=19
t critical = 2.09
Since t critical is GREATER than t calculated therefore we fail to reject null hypothesis H0.
From this we can conclude that We don't have enough or sufficient evidence to say that the mean working duration is different than 7.6 hours.
Answer:
A. $279,000
B. $27,900
Explanation:
A. Calculation for 2021 depletion of the timber tract
2021 Depletion=[($3,510,000 - $720,000) / 6.2 million] *$620,000
2021 Depletion=0.45x 620,000
2021 Depletion= $279,000
Therefore 2021 depletion of the timber tract is $279,000
B. Calculation to determine the depreciation of the logging roads
Depreciation=($279,000 / 6.2 million)*$620,000 Depreciation= 0.073*$620,000
Depreciation= $27,900
Therefore the depreciation of the logging roads is $27,900
Answer:
$577 Unfavorable
Explanation:
The calculation of spending variance for dye costs is shown below:-
Spending variance for dye cost = (Standard rate - Actual variable) × Actual units
= ($0.67 - $13,910 ÷ 19,900) × 19,900
= (0.67 - 0.69899) × 19,900
= $577 Unfavorable
Therefore for computing the spending variance for dye costs we simply applied the above formula.
