Answer #1

The null hypothesis, denoted H​​​​​​o, is the statement about the population parameter that is assumed to be true unless there is convincing evidence to the contrary .

So null hypothesis in a hypothesis test refers to default state of nature or status quo .

(Level of significance is alpha value , the population parameter which is denoted by sign "not equal" is aliter hypothesis and PROBABILITY of rejecting aliter hypothesis when it is false is PROBABILITY of committing type 2 error)

True or False 1. Hypothesis tests are robust to the significance level you choose, meaning regardless of the alpha level: .10, .05, or .01, our test will have the same conclusion or result. 2. If alpha is greater than the p-value, then we reject the null hypothesis. 3. The p-value is strictly the probability the null hypothesis being true. 4. Hypothesis tests are accessing the evidence provided by the data and deciding between two competing hypotheses about the population parameter....

Suppose you want to test H0: u <=100 against H1: u> 100 using a significance level of 0.05. The population is normally distributed with a standard deviation of 75. A random sample size of n = 40 will be used. If u = 130, what is the probability of correctly rejecting a false null hypothesis? What is the probability that the test will incorrectly fail to reject a false null hypothesis?

True or False: The higher the level of significance of a hypothesis test, the stronger the evidence we require to reject the null hypothesis. True or False: The purpose of a hypothesis test is to assess the evidence in favour of the null hypothesis. True or False: The higher the p-value of a hypothesis test, the more evidence we have to reject the null hypothesis.
