Question: 1) A study of estrogen levels in two different groups of women finds the following results (in pg/mL): Group A: 18.7 20.6 20.7 19.7 19.9

1) A study of estrogen levels in two different groups of women finds the following results (in pg/mL):

Group A: 18.7 20.6 20.7 19.7 19.9 19.4 20.2 21.6 18.8 14.1 21.6 16.2 21.7 20.8 19.3 21.3 1 9.9 20.8 23.2

Group B: 15.2 36.2 27.5 4.7 24.5 29.4 25.9 62.8

Some summary statistics to help you:

Group A:

_

y = 19.921

s = 2.0457

n = 19

Group B:

_

y = 28.275

s = 16.9169

n = 8

Is there a difference in estrogen levels? (Note:d.f.= 7.0864 for Welch'st-test). Use= 0.05.

2) Repeat (1), but this time assume equal variances. Use the same level ofyou used before.
