When you run SPSS for hypothesis testing, how do we determine that there is a significant evidence for an alternative hypothesis? Is there an alternative way to draw the same conclusion?
Homework Answers
There is a significant evidence for an alternative hypothesis when the p value for the test is less than 0.05
Another way of determining significance of alternative hypothesis is that accept Ha if the test statistic value is greater than the critical value for the given level of significance .
For eg., For a test of population mean, Accept Ha if tcal > tcrit

You've been assigned to do some hypothesis testing on the color of cars parked in the TCC parking lots. Your hypothesis testing will be based on using a proportion. Your think that the proportion of cars parked in the TCC parking lots are statistically the same as found throughout the world. Your instructions are to review 30 adjacent cars and determine the number of cars that are the color you were assigned. You have been assigned red color cars. Dupont...

1) A food distributor is being sued for racial discrimination because 12% of newly hired candidates are not white when 53% of all applicants were not white. You plan to use hypothesis testing to determine whether there is significant evidence that the company's hiring practices are discriminatory.

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?...
