lthy clients and contacted them to ask "On a scale of 1-100, how happy are you?"

(B) Approximately 95% of the wealthy customers at this firm have happiness ratings between 67.5 and 89.5.
(C) A wealthy customer selected at random from this population has a happiness rating between 67.5 and 89.5 95% of the time.
(D) About 95% of all random samples of 30 wealthy customers from this population would result in a 95 percent confidence interval of (67.5, 89.5).
(E) About 95% of all random samples of 30 wealthy customers from this population would result in a 95 percent confidence interval that captures the population mean happiness rating.
