Given two independent random samples with the following results:

n1=9 n2=10
x‾1=119 x‾2=142
s1=14 s2=18

Use this data to find the 95% confidence interval for the true difference between the population means. Assume that the population variances are not equal and that the two populations are normally distributed.

35 is an outlier

step-by-step explanation:

10.4 inches

step-by-step explanation:

2x2x2.6

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
