A confidence interval, at the 95% confidence level, will be used to answer the question, "What is the mean annual salary (in US dollars) of a Tesla car owner?" Data was collected from 36 Tesla owners across the US. The mean annual salary of those 36 Tesla owners was $254000. The standard deviation of ALL Tesla owners is known to be $1057. a) The value at the center of the confidence interval represents what quantity? Choose an option from the list and type its...
