The data table contains waiting times of customers at a bank, where customers enter a single waiting line that feeds three teller windows. Test the claim that the standard deviation of waiting times is less than 2.4 minutes, which is the standard deviation of waiting times at the same bank when separate waiting lines serve each teller window. Use a significance level of 0.01. Complete parts (a) through (d) below.Click on the icon to view the data.---a. Identify the null and alternative hypotheses. Choose the correct answer below.- A. \(H_0: \sigma = 2.4\) minutes; \(H_A: \sigma \neq 2.4\) minutes- B. \(H_0: \sigma < 2.4\) minutes; \(H_A: \sigma = 2.4\) minutes- C. \(H_0: \sigma \ge 2.4\) minutes; \(H_A: \sigma < 2.4\) minutes- D. \(H_0: \sigma = 2.4\) minutes; \(H_A: \sigma < 2.4\) minutes(No additional graphs or diagrams are present to be described.) **Customer Waiting Times**The table below provides data on customer waiting times, measured in minutes, across various instances. This can be used to analyze average waiting times, identify patterns, and assess service efficiency.| Time Interval 1 | Time Interval 2 | Time Interval 3 | Time Interval 4 ||-----------------|-----------------|-----------------|-----------------|| 8.8 | 7.6 | 10.3 | 7.8 || 6.1 | 7.6 | 7.2 | 7.5 || 7.8 | 6.7 | 6.8 | 6.2 || 6.7 | 6.8 | 6.3 | 7.1 || 6.4 | 8.9 | 11.6 | 6.7 || 7.7 | 8.5 | 7.9 | 4.8 || 7.4 | 7.4 | 7.7 | 6.1 || 7.9 | 6.3 | 6.8 | 7.8 || 6.5 | 9.1 | 6.1 | 6.9 || 6.1 | 6.8 | 6.2 | 6.1 || 8.3 | 6.1 | 7.1 | 7.2 || 6.4 | 8.1 | 8.5 | 6.9 || 6.8 | 6.9 | 8.9 | 6.5 || 6.6 | 6.5 | 6.1 | 7.1 || 7.4 | 8.4 | 7.1 | 6.3 |This data can assist in statistical analysis to improve operational efficiency, customer satisfaction, and overall service quality. Use this dataset to calculate the mean, median, mode, and range as part of a comprehensive statistical analysis.
