The hypothesis is usually a statement of no treatment effect the null hypothesis 3. A Type 1 Error is when we when it is true. 4.

Question 21 (4 points) For a hypothesis test about a population proportion or mean, if the level of significance is less than the p- value, the null hypothesis is rejected. (Ch10) True False Question 22 (4 points) Everything else being constant, increasing the sample size decreases the probability of committing a Type II error. (Ch10) True False The power of a statistical test is the probability of not rejecting the null hypothesis when it is true. (Ch10) True False Question...

True or False Question A random sample of 100 urban residents reveals that 50 believe in angels whereas in a random sample of 100 rural residents it is found that 65 believe in angels. We test the null hypothesis that the percentage of urban and rural residents who believe in angels is the same against the alternative that it is higher for rural residents. Based on this data, the corresponding test statistic is 2.165 and we reject the null hypothesis...

true or false
11. When the level of confidence and the sample size remain the same, a confidence interval for a population mean y will be narrower, when the sample standard deviation s is smaller than when s is larger. Chapter 10 12. The closer is the hypothesized mean is from the actual mean the higher is the power of the test. 13. The manager of the quality department for a tire manufacturing company wants to know the average tensile...

True or false. If the p-value is 6%, then we reject the null hypothesis and accept the alternative hypothesis at a significance level of 10% but not at a significance level of 5%. True or false?

Please explain, I dont really understand
7. True or False? The central limit theorem tells us that as the sample size increases, the sampling distribution of the sample mean approaches an approximately normal distribution REGARDLESS OF the original population data distribution. 8. True or False? Student t-distribution, regardless its degree of freedom, has heavier tails than the standard normal distribution. 9. In a hypothesis test we always assume the hypothesis unless we have sufficient evidence for the hypothesis 10. In...

True or False The model used for hypothesis testing of proportions is called a two-proportion z-test. True or False Beta (β) is the significance level which determines if the null hypothesis is rejected. True or False In business, the p-value is one of several factors in determining whether or not to reject a null hypothesis. True or False We could make a decision to reject a null hypothesis on a very low p-value or a very high z score.
