Question

a) I need to know the values of A,B,C,D,E,F,G,H

b) The appropriate critical t-statistic(s) used by SPSS default settings for this analysis is/are

c) Based on the 95% confidence interval, what would you conclude about the significance of the results in this study?

d) explain your conclusion in (b)

Paired Samples Statistics Std Deviation Mean 5.88878 4.40833 1.39403 Std. Errc Mean Pair 1 Pre 30.3000 10 Post A Paired Differences 95% Confidence Interval of the Difference Std Std. Error Sig Mean Deviation Mean Lower Upper df (2-tailed) Post-Pre 5.200004.61399 D 006

Explanation / Answer

a)

B = (4.40833/1.39403)^2 = 10
A = 30.3 - 5.2 = 25.1
C = 5.88878/sqrt(10) = 1.8622

D = 4.6139/sqrt(10) = 1.4591

E) Lower : 5.2 - 2.2622*1.4591 = 1.8992 where 2.2622 is t critical value at 5% los
F) Upper : 5.2 + 2.2622*1.4591 = 8.501
G) t = 5.2/1.4591 = 3.5638

H) df = 10-1 = 9

b)
Critical value of t is 2.2622

c)

In the 95% confidence interval, zero is not in the interval
Thus we conclude that there is not significance difference between pre and post means

d)
Here t value < t critical value, so we accept H0
Thus we conclude that there is not significance difference between pre and post means
