In hypothesis testing for a population mean, the term "significant difference" implies a:
A) difference between the sample mean and the hypothesized population mean that leads to the rejection of the null hypothesis.
B) difference between the test statistic and the critical region.
C) difference between the one-sided test and the two-sided test.
D) difference between the sample standard deviation and the population standard deviation.
Homework Answers
Answer is option A.
In testing problem for population mean to he tested our null hypothesis is taken as the population mean is equal to sample mean or there is no significant difference between the sample mean and population mean. And the alternative hypothesis is that there is significant difference between the sample mean and population mean. That means if there is significant difference between sample mean and population mean we reject the null hypothesis and accept the alternative hypothesis.

How do you know if a hypothesis test is testing the claim between 2 population proportions or 2 means? How is the test statistic for a claim about 2 population means, independent samples, standard deviations unknown, similar to the test statistic for 1 population mean, standard deviation unknown? If the difference between the 2 population means is not significant, which means the test statistic falls within the "usual" area of the distribution, what is the decision about the null hypothesis?...

For the standardized test statistic approach to hypothesis testing, calculate the test statistic for testing the null hypothesis that the population mean is less than or equal to 9.94, given a sample mean of 15.20, a sample size of 49, and a population standard deviation of 3.25. Round to two decimals.

These two groups are two samples representing the population of
workers in the economy. We want to know if the workers who take the
training (treatment sample) have higher earnings than the group
that do not take the training (control sample). If we find that the
trained workers have higher earnings it would indicate that the
training is effective.[1]In terms of statistics, we will do a
hypothesis test on the difference between the mean earnings in the
treatment population and...
