A bank with branches located in a commercial district of a city and in a residential area has the business objective of developing an improved process for serving customers during the noon-to-1 PM. lunch period. Management decides to first study the waiting time in the current process. The waiting time is defined as the number of minutes that elapses when the customer enters the line until he or she reaches the teller window. Data are collected from a random sample of 15 customers at each branch. Complete parts (a) through (d) below m Click the icon to view the bank branch data H P2 OC. Hgi 22 D.

### Bank Branch Waiting Time Analysis

A bank with branches in a commercial area and a residential area aims to improve customer service between noon and 1 PM. They examine waiting times by collecting data from random samples of 15 customers at each branch. Here's a detailed analysis of their findings:

#### Hypotheses
- **Null Hypothesis (H₀):** μ₁ = μ₂
- **Alternative Hypothesis (H₁):** μ₁ ≠ μ₂

#### Test Statistic
- Computed t-statistic: **tₛₜₐₜ = -4.09** (rounded to two decimal places)

#### Critical Values
- Critical values at a chosen significance level: **-2.06, 2.05**

#### Conclusion Options
- **A:** Reject H₀. There is insufficient evidence that the mean waiting times differ.
- **B:** Do not reject H₀. There is sufficient evidence that the mean waiting times differ.
- **C:** Reject H₀. There is sufficient evidence that the mean waiting times differ.
- **D:** Do not reject H₀. There is insufficient evidence that the mean waiting times differ.

#### p-value
- Computed p-value: **0.0001** (rounded to three decimal places)

Choose the appropriate conclusion based on the test statistic and p-value.

#### Interpretation Options
- **1:** Probability of obtaining a sample with a t-statistic in either direction if no difference exists.
- **2:** Probability of obtaining a sample with a t-statistic in the negative direction if no difference exists.
- **3:** Probability of obtaining a sample with a t-statistic more extreme in either direction if no difference exists.

#### Confidence Interval for Mean Difference
- Construct a 95% confidence interval for population mean differences.
- Computed interval: **(-1.54, -0.84)** (rounded to two decimal places)

#### Confidence Interval Interpretation
- **A:** Difference falls above the upper limit.
- **B:** Difference lies within the interval.
- **C:** Difference falls below the lower limit.
- **D:** Difference lies outside the interval.

#### Waiting Time Data (in minutes)
- **Commercial Branch:**
