Answer:
lower range 33.822 years
upper range 38.178 years
Explanation:
step 1:
48 -1 = 47
step 2:
(1 - 95%) / 2 = 0.025
step 3:
we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117
step 4:
divide sample standard deviation by square root of sample size
7.5 years / √48 = 7.5 / 6.9282 = 1.0825
step 5:
multiply results from step 3 and 4
2.0117 x 1.0825 = 2.178
step 6:
for the lower range, subtract step 5 from sample mean
36 - 2.178 = 33.822
step 7: for the upper range, add step 5 with sample mean
36 + 2.178 = 38.178
Answer: The actual value
Explanation: In simple words, actual value refers to the utility satisfaction that a customer receives after purchasing a product.
The only difference between perceived value and actual value is that while calculating perceived value the customer compares his product with other product . However, while calculating actual value he only compares the existing performance with his or her expectations.
In the given case, Jeremy feels the product he buy is no as useful as he thought. Hence it lacks actual value.
Answer:
d. $1,540 F
Explanation:
The formula to compute the variable overhead efficiency variance is shown below:
= (Actual direct labor hours - standard direct labor hours) × variable overhead per hour
where,
Actual direct labor hours is 2,380
And, the standard direct labor hours equal to
= 5,200 units × 0.5
= 2,600 hours
Now put these values to the above formula
So, the value would equal to
= (2,380 hours - 2,600 hours) × $7
= 1,540 favorable
