Question
Using this material, identify the following information t-test result for each set of 1. What is the mean for each of the two groups? Identify this clearly. 2. Interpret the results of the t-test. Is there a significant difference between the means for the two groups? Important: Explain how you know if the difference is significant or not. Which group has a greater number of siblings?

Equal variances not 1354 443.014 176 .21375 ,15784 assumed 53118 ,10367 ,09646Explanation / Answer
1:
Mean of Males: 3.4133
Mean of females: 3.6271
P-value of F test shows the variances are equal.
So t -test statistics for comparing mean is:
t = -1.322
P-value is 0.187.
Since p-value is greater than 0.05 so difference between the groups is not significant.
3:
The t test statistics is negative it shows male groups has lower mean. But p-value shows that difference is bot significant. That is we can conclude that both groups has equal mean.
----------------------------
1:
Mean of Males: 4.6933
Mean of females: 4.4137
P-value of F test shows the variances are equal.
So t -test statistics for comparing mean is:
t = 2.875
P-value is 0.004
Since p-value is less than 0.05 so difference between the groups is significant.
3:
The t test statistics is positive it shows male groups has greater mean.
------------------------------
1:
Mean of Males: 2.5733
Mean of females: 3.0853
P-value of F test shows the variances are not equal.
So t -test statistics for comparing mean is:
t = -3.713
P-value is 0.000
Since p-value is less than 0.05 so difference between the groups is significant.
3:
The t test statistics is negative it shows female groups has greater mean.
