A researcher wants to estimate the mean response time of two different customer service teams, Team A and Team B, to customer inquiries. The researcher collects random samples from both teams and calculates the sample means and standard deviations. Based on the data collected, the researcher wants to construct confidence intervals for the mean response times of both teams and compare them. Select all correct statements about confidence intervals and their interpretation. Group of answer choices If two confidence intervals overlap, it indicates a significant difference between the mean response times of Team A and Team B. The width of a confidence interval is influenced by the sample size and the variability of the data. A wider confidence interval indicates a higher level of confidence. The confidence level represents the probability that the population parameter falls within the confidence interval. Increasing the sample size will decrease the width of the confidence interval
