Give a correct interpretation of a 99% confidence level of 0.328 < μ < 0.486.

a. 99% of sample means fall between 0.328 and 0.486.

b. there is a 99% chance that the true value of μ will fall between 0.328 and 0.486.

c. we are confident that 99% of values between 0.328 and 0.486 represent the true value of the population mean μ.

d. we are 99% confident that the interval from 0.328 to 0.486 actually does contain the true value of the population mean μ.
