Solution Steps

Step 1: Identify the Grouping Criterion

The population is divided into smaller groups or subgroups based on dormitory. This could be based on geographical location, class, age group, etc.

Step 2: Determine the Selection Method within Groups

Units within these groups are selected using a random method.

Step 3: Assess the Selection Unit and Number of Units Selected

Understanding whether a few members (10 per group) from each group are selected, suggesting a stratified sampling approach if the selection within groups is random.

Step 4: Evaluate the Number of Groups

The number of groups chosen is multiple, and whether they are chosen randomly or systematically can influence the identification of the sampling technique.

Final Answer: The sampling technique used is likely Stratified Sampling.

Over the years, a sushi restaurant has had a mean customer satisfaction rating of 71.2 with a variance of 25.4. The owner wants to see if using a new menu will have any effect on the variance, σ^2. The owner surveys a random sample of 14 customers who ordered from the new menu. For the customers surveyed, the variance of ratings is 46.2. Assume the ratings for customers who order from the new menu follow a normal distribution. Is there enough evidence to conclude that the population variance, σ^2, differs from 25.4? To answer, complete the parts below to perform a hypothesis test. Use the 0.10 level of significance. (a) State the null hypothesis H0 and the alternative hypothesis H1 that you would use for the test. H0: H1: σ s < ≤ > ≥ = ≠ × 5 (b) Perform a chi-square test. Here is some information to help you with your test. - χ0.95^2 is the value that cuts off an area of 0.05 in the left tail of the distribution, and χ0.05^2 is the value that cuts off an area of 0.05 in the right tail of the distribution. - The value of the test statistic is given by χ^2 = (n-1) s^2 / σ^2.
