A fast-food chain sells drinks that they call HUGE. When we take a sample of 36 drinks and weigh them, we find that the mean is 39.7 ounces with a standard deviation of 1.6 ounces.
a. A technology input menu for calculating a confidence interval requires the sample mean, $\bar{x}$, the sample standard deviation, Sx, and the sample size, $\mathrm{n}$. State how you would fill in these numbers.
b. Report the confidence interval in a carefully worded sentence
a. Fill in the values below for $\bar{x}, S x$, and $n$.
$\bar{x}: \square$
Sx: $\square$
$\mathrm{n}: \square$
(Type an integer or a decimal. Do not round.)
Answer
Final Answer: \(\bar{x}: \boxed{39.7}\)\(Sx: \boxed{1.6}\)\(n: \boxed{36}\)
Step 1 ：The question is asking for the sample mean, the sample standard deviation, and the sample size. From the problem, we know that the sample mean is 39.7 ounces, the standard deviation is 1.6 ounces, and the sample size is 36. We can directly fill in these values.
Step 2 ：Final Answer: \(\bar{x}: \boxed{39.7}\)\(Sx: \boxed{1.6}\)\(n: \boxed{36}\)
