Question

You study average spending on a week's vacation. You take two independent samples. Sample 1 of 61 people has a mean of $1,612 with a variance of $4,125. Sample 2 of 52 people has a mean of $1,576 with a variance of $3,384. Assume population means are equal at $3.754 Calculate the z-statistic.

Step 1

Step 1: The formula for the z-statistic is: $$z = \frac{(\bar{x}_1 - \bar{x}_2) - (\mu_1 - \mu_2)}{\sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}}}$$ where: * $\bar{x}_1$ is the sample mean of the first sample * $\bar{x}_2$ is the sample mean of the second sample * Show more…
