Question

A research is conducted on the number of times Thais and Chinese who live alone buy Alcoholic drinks in a month. Assume that the distributions follow the normal probability distribution and the population standard deviations are equal. The information is summarized below.

Statistic	Thais	Chinese
Sample mean	25.17	22.50
Sample standard deviation	5.69	4.51
Sample size	34	36

At the 0.01 significance level, is there a difference in the mean number of times Thais and Chinese order alcoholic drinks in a month?

1. State the decision rule for 0.01 significance level: H₀: μ_thais= μ_chinese H₁: μ_thais ≠ μ_chinese_. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)

2. Compute the value of the test statistic. (Round your answer to 3 decimal places.)

3. What is your decision regarding the null hypothesis?

4. What is the p-value? (Round your answer to 3 decimal places.)
