Sam is planning to open a dockless scooter company in Fayetteville and wants to estimate the amount of time a typical user would rent one. She visits a similar college town to investigate, where she randomly samples 20 customers and asks each to report the number of minutes the scooter was used. The average rental time was 142.21 minutes. Sam knows from national data that scooter rental time is a normally distributed variable with a standard deviation of 26.09 minutes. What would happen to the confidence interval if Sam sampled an additional 100 customers to the sample? a. It would probably not change b. It would get wider c. Sample size does not impact the width of the confidence interval d. It would become narrower
