Question

Use the given degree of confidence and sample data to construct a confidence interval for the population mean μ. Assume that the population has a normal distribution The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.4 15.6 15.0 15.1 15.3 15.4 15.9 15.9 Construct a 98% confidence interval for the mean amount of juice in all such bottles OA. 15.10 oz<p<15.80 oz O B. 15.00 oz<p < 15.90 oz OC. 15.90 oz<H15.00 oz D. 15.80 oz < μ < 15.10oz Click to select your answer.

Answer 1

The statistical software output for this problem is:

One sample T confidence interval:
μ : Mean of variable

98% confidence interval results:

Variable	Sample Mean	Std. Err.	DF	L. Limit	U. Limit
Data	15.45	0.11801937	7	15.096184	15.803816

Hence,

15.10 oz < $\mu$ < 15.80 oz

Option A is correct.
