Hint eTextbook and Media (el Interpret this interval in context. 쓸 we are 99 confident that the people in the sample had 3-PBA concentrations between 15 and 35 units higher hen eating on organic than when eating organic. We are confident that 99% of people have 3 PBA concentrations between 15 and 35 units higher when eating non-organic than he eatingo ganic. we are 99% confident that all people will have mean 3 PBA concentrations between 15 and 35 units higher when eating non organic than when eatingorganK. Between 15% and 35% of people have higher concentrations of 3-PBA when eating non organic than when eating organic. ● we are 99% confident that the people in the sample had mean 3 PBA concentrations between 15 and 35 units higher when eating non-organic than when eating organic.

6. Give a correct interpretation of a 99% confidence level of 0.328 <p < 0.486. (1 point) We are 99% confident that the interval frorn 0 328 to 0 486 actually does contain the true value of the population mean μ There is a 99% chance that the true value ofμ will fall between 0 328 and 0 486. 99% of sample means fall between 0328 and 0486.
