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:
D. not change demand or supply in the labor market.
Explanation:
As people is finding new jobs in the same industry, it can be said that there is no evident change in the demand of labor neither in the supply of labor.
Job turnover can be high or low, not necessarily related to a variation in demand or jobs offers.

C) The chronological context
Explanation:
Chronological context refers to time related factors that affects affects communication. The effect could be favourable or unfavourable.
In this scenario because Andy had worked for a long time and he feels he is hard working, he feels he deserves a pay raise.
His need for a pay raise is time based. It is initiated by his length of service in the company. So this is a chronological context in which a time based factor affects communication between Andy and Anna.
