Description: One sample of n = 10 scores has a variance of s2 = 6 and a second sample of n = 10 scores has a variance of s2 = 8. The pooled variance for these two samples will be the following.a. 14b.8 c.6d.7

One sample of n = 10 scores has a variance of s2 = 6 , and a second sample of n = 10 scores has a variance of s2 = 8. Pooled variance = (n1-1)s12+(n2-1)s22(n1+n2-2)Pooled variance =(10-1)(6) + (10-1)(8)(10+10-2)Pooled variance =54 + 7218Pooled variance =12618Pooled variance =7 Option (d) is correct.Thank you..!!
