Mean: M = =

Level α = 1-0.90 = 0.10.

90% confidence interval for the women= M ±CV (t-value) X
Hypothesis test:

df = + - 2

df = 18

1. The null hypothesis ( ) : - = 0
1. The alternative hypothesis ( ) : ≠ 0
1. The critical value : t = ± 2.101
1. The test statistics : Detail calculations
Pooled variance: = = = = 8.23 This is just a sample!
Estimated standard error: = =
= = = 1.31(you will have different answer)
The t statistics: t = = = = -2.48 (you will have different answer)
The test statistics: = -2.48 (you will have different answer)
