### Analysis of Customer Waiting Times at BanksThe table below presents customer waiting times (in minutes) for two different banks. These times reflect the variations in service line structures at each bank.#### Waiting Times for Customers- **Bank A**: 6.3, 6.6, 6.7, 6.8, 7.1, 7.2, 7.5, 7.7, 7.7, 7.7 - At Bank A, customers enter a single waiting line that feeds into three teller windows.- **Bank B**: 4.2, 5.4, 5.8, 6.3, 6.6, 7.7, 7.7, 8.4, 9.4, 10.0 - At Bank B, customers may enter any of three separate lines, each leading to a different teller window.#### Statistical AnalysisTo assess the consistency of waiting times, we will construct a 99% confidence interval for the population standard deviation of waiting times at Bank A. This interval will provide insight into the variability customers might expect.- Use the provided chi-square critical values table to aid in the calculation.#### InstructionsCalculate the confidence interval for the standard deviation (σ) at Bank A:\[ \text{min} < \sigma_{\text{Bank A}} < \text{max} \]- Results should be rounded to two decimal places as needed.This analysis helps in understanding service efficiency and can guide improvements in customer experience strategies.

IQ scores among the general population have a mean of 100 and a standard deviation of 14. A researcher claims that the standard deviation, o, of IQ scores for females is not equal to 14. A random sample of 24 IQ scores females had a mean of 98 and a standard deviation of 11. Assuming that IQ scores for females are approximately normally distributed, is there significant evidence (at the 0.05 level of significance) to conclude that the researcher's claim is correct?

Assume all populations are normally distributed. A travel analyst claims that the mean price of a round trip flight from New York City to Los Angeles is less than $507. In a random sample of 55 round trip flights from NYC to LA, the mean price is $502. Assume the population standard deviation is $111. At α = 0.05, is there enough evidence to support the travel analyst’s claim?
