Please use the following information to answer questions2a-2c:

One sample (n1) has SS= 70 and a second sample (n2)has SS= 42.

2a.Find thesample variance for n1,ifn1= 8(MUST SHOW WORK FOR THIS PROBLEM).

2b. Findthe sample variance forn2, if n2 = 4(MUST SHOW WORK FOR THIS PROBLEM).

2c.Calculate the pooled variance for both samples (MUST SHOW WORK FOR THIS PROBLEM).

2d.Due to the fact that these samples have a differentsize,what is trueabout the calculated pool variance?

1. The pooled variance is closer to the variance for the smaller sample.

2. The pooled variance is exactly halfway between the two sample variances.
