Answer:
differences
Explanation:
a pretest/protest experimental design is that which involve the taking down or recording down of measurements before and after a treatment.pretest-posttest designs are a more suitable experimental design that is usually used when comparing participant groups and also measuring the differences or the degree of change that happens as a result of treatments. there are various forms/ways of analyzing an experimental data of which there is the t-test. t-test is usually used to measure the differences between two groups in an experiment.
comparison of the differences as a form of data analysis of the two variable(husband/wife) in a pretest/protest design using the t-test will show you if its a directional hypothesis or a non directional hypothesis and also clearing shows the relationship when comparing the two variables.
Answer: Offset their losses with gains
Explanation:
Diversification reduces the risk of losses because it spreads investment out across different industries that are ideally negatively correlated so that if things in one industry go wrong for instance, things will go right in the other.
For instance, the investor could invest in both Ice cream companies and Hot Beverage companies with the idea being that in winter when the Ice Cream company losses sales, the Hot Beverage company would make up for it and vice versa in the summer.
Diversification therefore works by offsetting losses in one investment with gains in another.
Answer:
Damage to the atmosphere can occur from the use of some cleaning products, including aerosol sprays
Explanation:
Damage to ozone layer is mainly because of aerosol sprays. Aerosols have a huge environmental effect, as they, like greenhouse gasses, can alter the Earth's 'radiative/energy balance. By changing the amount which is absorbed into the atmosphere & the amount that is dispersed back into space, the amount of energy from the sun can be controlled by aerosols.
As they contain compressed & hydrocarbon fuels, aerosol sprays increase the carbon footprint. Aerosol sprays can also emit VOCs that, a big cause for asthma-inducing pollution, and that adds to the ground-level ozone levels.
