Answer:
The candidate should get 5829 votes.
Step-by-step explanation:
This is a proportion question. The ratio should hold for both the pole and the actual vote.
Equation
x /9570 = 67/110 Multiply both sides by 9570
x = 67 * 9570 / 110 Multiply the two numerators.
x = 641190 / 110 Divide by 110
x = 5829
Answer: the company should promote 4412 hours for these bulbs.
Step-by-step explanation:
Assuming that the lives of the bulbs are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = lifetime of the bulbs in hours.
µ = mean hours
σ = standard deviation
From the information given,
µ = 4000 hours
σ = 200 hours
If only 2% burn out, then the company would promote 98% would meet the claimed lifetime. Looking at the normal distribution table, the z score corresponding to a probability of 0.98 is 2.06. Therefore,
2.06 = (x - 4000)/200
Cross multiplying, it becomes
200 × 2.06 = (x - 4000)
412 = x - 4000
x = 4000 + 412
x = 4412 hours
