Question

10-2. The following information is based on independent random samples taken from two normally distributed populations having equal variances: $n_1 = 24$ $\bar{x}_1 = 130$ $s_1 = 19$ $n_2 = 28$ $\bar{x}_2 = 125$ $s_2 = 17.5$ Based on the sample information, determine the 95% confidence interval estimate for the difference between the two population means.

          10-2. The following information is based on independent
random samples taken from two normally distributed
populations having equal variances:
$n_1 = 24$
$\bar{x}_1 = 130$
$s_1 = 19$
$n_2 = 28$
$\bar{x}_2 = 125$
$s_2 = 17.5$
Based on the sample information, determine the 95%
confidence interval estimate for the difference between

random samples taken from two normally distributed
populations having equal variances:
n1 = 24
x̅1 = 130
s1 = 19
n2 = 28
x̅2 = 125
s2 = 17.5

Step 1

The formula for the standard error of the difference between two sample means is: SE = sqrt((s₁²/n₁) + (s₂²/n₂)) where s₁ and s₂ are the standard deviations of the two samples, and n₁ and n₂ are the sample sizes. In this case, s₁ = 19, s₂ = 17.5, n₁ = 24, and Show more…
