Consider a hypothesis test of H0: μ = 0 against H1: μ > 0 where μ is the mean percent change in total body bone mineral content of young women. The population standard deviation is σ = 2. The level of significance for the test is α = 0.05.
You are presented a 90% confidence interval for the difference in population mean scores (with drug - without drug) of (-17.81, -7.24). What can you conclude from this interval?
use the following sample data to test whether the GPA are different at the 0.05 level of significance.
It is suspected that the mean turnover has changed and is not 6.0. Use the .05 significance level. Give the formula for the test statistic.
Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?
At.01 level of significance, is proportion of seeds which germinate dependent on seed type?
For a normal distribution, find the z-score value that separate the middle 90% of the distribution from the 10% in the tails.
Data is given in the table below. Process data as illustrate in the paper on the Mann-Whitney U test. Critical Value:Test Statistic (Show procedure.)Z .
Using the 0.01 significance level, can we conclude that there is a positive correlation between the variables?
Do the data indicate a significant difference between the frequency distributions for male and females? Test at the .05 level of significance and describe the difference.
