I need help with a STAT question that is in the screenshots below:

:) From a random sample You have computed that a condence interval for ,u is given by: What does the symbol p. stand for? What does the symbol 1? stand for? 9 0; What does the Symbols stand for? Does increasing the condence level lead to a larger value of t', a smaller value of t', or no change in the value of t'? 9 Does increasing the sample size lead to a larger value of t\a mu?? 2 a O 0 000000 the number of samples taken the sample standard deviation the population standard deviation the sample size the population mean ("the truth") the sample proportion the population proportion ("the truth") the sample mean a xba r?? o O 000 the population standard deviation the sample size the sample standard deviation the number of samples taken the population mean ("the truth") JUITIVICU LUNCH O the population mean ("the truth") O the sample mean O the sample proportion O the population proportion ("the truth") 4 s??
