Question

Use this information for the next several questions. A sample of 10 participants was given an experimental treatment. Test whether the sample represents a population that is different from the general population. The sample of 10 had a mean of 49. The general population of individuals has a mean of 44, a standard deviation of 6, and follows a normal curve. Carry out a Z test using the five steps of hypothesis testing with a two-tailed test at the 0.05 significance level, and identify a drawing of the distributions involved. Figure the 95% confidence interval. Question 18 (1 point) Determine a research hypothesis and a null hypothesis (for the information above). Choose the correct answer below. The research hypothesis is the means of the populations are not the same. The null hypothesis is the means of the populations are the same. The research hypothesis is the mean of the sample population is less than the general population. The null hypothesis is the mean of the general population is less than the sample population. The research hypothesis is the means of the populations are the same. The null hypothesis is the means of the populations are not the same. The research hypothesis is the means of the populations are the same. The null hypothesis is the mean of the general population is less than the mean of the sample population.
