The US Census Bureau gathered data regarding yearly gas sales for residents of different states. Wyoming was the highest, at average of $4,505 per capita in gas sales. A 95% confidence interval for yearly gas sales of Laramie residents was calculated to be $3,850 < μ < $4,550. Indicate which of the following statements are correct.

95% of all Laramie residents will spend between $3,850 and $4,550 per year on gas.

if 100 confidence intervals were done, 95 would get an interval between $3,850 and $4,550

A new confidence interval has 95% probability of being between $3,850 and $4,550
