Labor-saving devices are inventions that reduce the time and effort needed to perform or complete a task. Farm equipment, home appliances and construction equipment are examples of mechanical inventions that save time and physical labor.
Answer:
Explanation:
Reading literature enables us to see the world through the eyes of others. It trains the mind to be flexible, to comprehend other points of view—to set aside one's personal perspectives to see life through the eyes of someone who is of another age, class, or race.
Answer:
If I were forced to go into hiding I would wear many layers of cloths like five to six shirts and two to three leggings, a jacket with a lot of pockets and more under clothes. I would do this so I can wear fresh clothes as long as possible and the pockets on the jacket could help me carry more stuff like a phone or charger so I could contact friends and family and go live with them. I would also get my shoes because my slippers would break easily. In my sack I would carry as much as food I can so I would not starve to death. I would bring medicine so if my family got sick or injured they could heal faster and my important documents like ID and passport because when the Holocaust were to end I would flee to another country and I would really need them.

A statistical hypothesis is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.[1] A statistical hypothesis test is a method of statistical inference. Commonly, two statistical data sets are compared, or a data set obtained by sampling is compared against a synthetic data set from an idealized model. A hypothesis is proposed for the statistical relationship between the two data sets, and this is compared as an alternative to an idealized null hypothesis that proposes no relationship between two data sets. The comparison is deemed statistically significant if the relationship between the data sets would be an unlikely realization of the null hypothesis according to a threshold probability—the significance level. Hypothesis tests are used in determining what outcomes of a study would lead to a rejection of the null hypothesis for a pre-specified level of significance. The process of distinguishing between the null hypothesis and the alternative hypothesis is aided by identifying two conceptual types of errors (type 1 & type 2), and by specifying parametric limits on e.g. how much type 1 error will be permitted.
An alternative framework for statistical hypothesis testing is to specify a set of statistical models, one for each candidate hypothesis, and then use model selection techniques to choose the most appropriate model.[2] The most common selection techniques are based on either Akaike information criterion or Bayes factor.
Statistical hypothesis testing is sometimes called confirmatory data analysis. It can be contrasted with exploratory data analysis, which may not have pre-specified hypotheses.
