Answer #1

Here the test statistic H is based on squared values. So it is not possible to have a negative value for that. It may be possible that you have done some calculation mistake. I recommend you to do all the mathematics from the beginning in a fresh paper.

Another thing the critical value can't be a negative a chi-squared distribution takes only positive value in its range. I would suggest you to use a calculator to do all the maths, and while calculating the chi-squared critical value you can use a chi-squared table or refer some online chi-square critical value calculator.

[Recommend: Do all the mathematics from the beginning in a fresh paper.]

Write a paragraph explaining the following inferential statistical results: The results of a Kruskal-Wallis test were significant (X2(4)= 57.56, p <.001)  between the following two statements (360 leaders and supervisors answered the survey questions): Statement 1:  As a successful leader, I always think that the best decision will be the one with the largest consensus. Statement 2. As a leader, I do not discuss my decisions with my employees; I just tell them what they have to do.

This problem is the check to see whether you understand the X-squared test. There are only 2 test columns, so you cannot use the X-squared Goodness of Fit applet from the previous problem as it requires 3 or more test intervals. You are told that a genetics theory says the ratio of tall:short plants is 3:1. You test this claim by growing 200 plants. You obtain 160 tall plants and 40 short plants. Using a X-squared test, determine whether or...

There was a lawsuit against Starbucks claiming that their lattes are being under filled. We know that a grande size cup should be 16 oz. The Today Show decided to do a test to see if they actually are being under filled. They went out and got 6 lattes and found that the average amount of liquid in each was 13.22 oz, with a sample standard deviation of 2.05. We are interested in determining if there is evidence that the...

What did I do wrong on this question? A 0.2-kg ball is bounced against a wall. It hits the wall with a speed of 20 m/s at a 35 degree angle and rebounds elastically at a 35 degree angle. What is the magnitude of the change in momentum of the ball in the horizontal direction? I found v1 =-20 V2= 20 -20(cos35)=-16.4 20(cos35)=16.4 I then took 16.4-(-16.4) and multiplied that by 0.2, and got 6.56, however, I was told the...
