Answer #1

Sol:

TRUE

inferential statistics is decision, estimate, prediction, or generalization about a population based on a sample.

A population is a collection of all possible individuals,objects ,or measurements of interest

A sample is a subset of popualtion.

we take the sample and conclude about population.

Ex :average US salary is $100000.

we can deny or accept this statement

Take the random sample of say 50 US citizens and find sample mean,sample standard deviation.

calculate t statistic ,p value and then conclude about population

TRUE

Which of the following statements about hypothesis testing is true? If the data provide sufficient evidence for the alternative hypothesis, then the conclusion is to reject H0. A hypothesis test provides a plausible range of values for a parameter. If the data provide sufficient evidence for the null hypothesis, then the conclusion is to reject H1. A hypothesis test uses sample data to determine which of two competing hypotheses is true. For a two-sided hypothesis test in which the test...

Based on the information provided for this hypothesis testing, what decision should you come to? (Assume that the population is normally distributed). Note that you need to complete the 5 step hypothesis testing. Be sure to include the cut-off sample score, the sample score on the comparison distribution, and the conclusion you reach. Mean=5, SD=1, Sample Score=7, .05 level of significance, one-tailed.

The procedures for (1) determining confidence intervals to estimate the mean and (2) hypothesis testing based on the difference between one sample mean and a test value or on the difference between two sample means both rely on sampling distributions. Explain why sampling distributions are important for each procedure.

True                 b.   False If the claim is that a population parameter is not a specific value, the particular type of problem would be considered a one-tailed test.

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....
