Which one the following statement is the required assumption for t-test?
- A large sample size.
- The data follow a normal distribution.
- A known population standard deviation.
- A small sample size.
Homework Answers
A small sample size is required assumtiass of t-test, because the sample size is large then we use z-test and sample size is small we use the t-test.

If a sample size (n) is small, a true effect (g., a true difference between the sample mean and population mean) might be __________ even though the true effect __________ . missed; is real missed; is not real detected ; is real detected; is not real There is no relationship between sample size and likelihood of missing the effect. Unlike a z-test, a one sample t-test can be used when: sample size is large population is not known to be...

3. Testing a population mean The test statistic (Chapter 11) Aa Aa You conduct a hypothesis test about a population mean u with the following null and alternative hypotheses: Ho: u-25.8 H1: <25.8 Suppose that the population standard deviation has a known value of a observations, which provides a sample mean of % 30.7. 17.8. You obtain a sample of n =62 Since the sample size large enough, you assume that the sample mean X follows a normal distribution. Let...

Which of the following statements about the sampling distribution of the sample mean, x-bar, is not true? The distribution is normal regardless of the shape of the population distribution, as long as the sample size,n, is large enough. The distribution is normal regardless of the sample size, as long as the population distribution is normal. The distribution's mean is the same as the population mean. The distribution's standard deviation is smaller than the population standard deviation. All of the above...
