Answer:
about 68% of brand x’s batteries have a lifespan between 95.2 hours and 108.8 hours. about 68% of brand y’s batteries have a lifespan between 98.6 hours and 101.4 hours. the life span of brand y’s battery is more likely to be consistently close to the mean.
Explanation:
According to the empirical rule (68–95–99.7 rule) for a normal distribution, 68% of the data falls within the first standard deviation (μ ± σ).
Given for brand x, mean (μ) = 102 hours and standard deviation (σ) = 6.8 hours.
first standard deviation (μ ± σ) = 102 ± 6.8 = (95.2, 108.8)
about 68% of brand x’s batteries have a lifespan between 95.2 hours and 108.8 hours.
Given for brand y, mean (μ) = 100 hours and standard deviation (σ) = 1.4 hours.
first standard deviation (μ ± σ) = 100 ± 1.4 = (98.6, 101.4)
about 68% of brand x’s batteries have a lifespan between 98.6 hours and 101.4 hours.
Since the standard deviation of brand y is smaller than that of brand x, brand y battery is more likely to be consistently close to the mean
Answer:
Option (a) is correct.
Explanation:
According to the law of diminishing marginal productivity, if there is an increase in the input in the production of a certain commodity then as a result there is an increase in the output of that commodity, initially but further increase in the input will have no impact on the output of the commodity or will have a negative impact.
In our case, when farmer hires 3rd worker, the output increases by 1,400(4,400-3,000) bushels. According to the law of diminishing marginal productivity, if he hires 4 workers then there is an increase in the output but less than the 1,400 bushels.
This condition will be satisfied in the option (a), where output increases by 1,200 bushels.
