What percentage of people falls between -2 and +2 standard deviations on IQ scores ( if the general population of IQ scores assumes a normal distribution )?
You take a sample of 22 from a population of test scores and the mean of your sample is 60. A) you know the standard deviation of the population is 10.
Two samples, each with n = 16 scores, produce an estimated standard error of 4 points and a t statistic of t = 2.00. What is the sample mean difference?
The data from an independent-measures research study produce a sample mean difference of 6 points and an estimated standard error of 2 points. If there are n = 8 scores in each sample, what is the value for the t statistic?
Does this engine satisfy the increase of entropy principle? B) If the thermal efficiency of the heat engine is increased to 70 percent, will the increase of entropy principle still be satisfied?
Which set of sample characteristics is most likely to produce a significant value for the independent-measures t statistic and a large measure of effect size?
You were interested in how long the average psychology major at your college studies per night, so you asked 10 psychology majors to tell you thee amountt they study. They told you the following times: 2, 1.5, 3,2,3.5,1, 0.5, 3, 2, 4. A) Find the
Calculate the flow of gas in pounds per minute at the point of injection if the gas upstream of the point of injection is 100% CH4. Unfortunately for you, the gas upstream of the point of injection of CO2 already contained 1.0 % CO2.
How does the t distribution compare with normal distribution? How does this difffference affect the size of Confidence Interval constructed using z relative to those constructed using t? Does the sample size make a difference?
