Answer:
95% confident that the true proportion of service contracts sold on treadmills versus exercise bikes is between -0.1969 and 0.02689.
Explanation:
S1 = number of service contracts for sold treadmills
S2 = number of service contracts for sold Exercise Bikes
P1 = 67/185 = .362162
P2 = 55/123 = .447154
P=n1p1 +n2p2/ n1 + N2 = 185*.362 + 123*.447/ 185 + 123 = .3961
Standard Error = .0571
Margin of Error = E = Za/2 * Se = 1.96 * .0571 = .1119
Lower Limit = (P1 – P2) – E =(.362 - .447) - .1119 = -.1969
Upper Limit = (P1 – P2) + E = (.362 -.447_ + .1119 =.02691
Therefore 95% confident that the true proportion of service contracts sold on treadmills versus exercise bikes is between -0.1969 and 0.02689.
Answer:
a. 32 secs
b. 3.75 or 4
Explanation:
The computation is shown below:
(a) Cycle Time is
= Operation time per week ÷ output per week
= (40 hours × 60 × 60) ÷ (4,500)
= 32 secs
(b) And, the Theoretical minimum number of workstations required is
= Sum of total task times ÷ cycle time
= (22 + 30 + 15 + 14 + 12 + 27) ÷ (32 sec)
= 3.75 or 4
By applying the above formulas we can get the cycle time and the theoretical minimum number of work stations
Answer:
company's inventory increase = $28962
so correct option is D. increased by $28,962
Explanation:
given data
purchase of inventory = $30,000
returned = $600
credit paid = $150
to find out
the company's inventory will be
solution
company's inventory increase here by
so we know = purchase - returned - discount + credit paid
= 30000 - 600
= $29400
and discount = 2% of 29400 = 588
so company's inventory increase = 29400 - 588 + 150
company's inventory increase = $28962
so correct option is D. increased by $28,962
