SOLUTION:

From given data,

In what exact scenarios would the "null hypothesis" be either rejected or accepted?

The typical approach for testing a null hypothesis is to select a statistic based on a sample of fixed size, calculate the value of the statistic for the sample and then reject the null hypothesis if and only if the statistic falls in the critical region other wise it will be accept.

What exactly does it mean?

Rejecting or accepting the null hypothesis on the basis of some test, but not of accepting the null hypothesis or the alternative hypothesis.

Often in an experiment we are actually testing the validity of the alternative hypothesis by testing whether to reject the null hypothesis.

In a hypothesis test, the null hypothesis of < 81 is rejected because the P-value was 0.0465. The sample size “n” was 55 and the sample mean was 84.5. Find the value of the population standard deviation “σ”.

1) Which of the following statements are true? If the null hypothesis is rejected at the 1% level of significance, then it will be rejected at 5% of level of significance. For a given confidence level, halving the margin of error requires a sample twice as large. For a specified confidence level, larger samples provide smaller margins of error. a) Ionly b) IIonly c) IIIonly d) IandIIonly e) IandIIIonly 2) Suppose that you take random samples of size n from...

a) If sample data are such that the null hypothesis is rejected at the alpha=5% level of significance based upon a 2 tailed test, is H0 also rejected at the alpha=1% level of significance ? Explain. b) If a 2 tailed hypothesis test leads to rejection of the null hypothesis at a certain level of significance, would the corresponding 1 tailed test lead to rejection of the null hypothesis ? Explain.

A) If sample data are such that the null hypothesis is rejected at the alpha=5% level of significance based upon a 2 tailed test, is Ho also rejected at the alpha=1% level of significance? Explain. B) If a 2 tailed hypothesis test leads to rejection of the null hypothesis at a certain level of significance, would the corresponding 1 tailed test lead to rejection of the null hypothesis? Explain.
