A 99% confidence interval for the mean μ of a population is computed from a random sample and found to be 6 ± 3. We may conclude
valentina_108 [34]

Answer:

A. there is a 99% probability that μ is between 3 and 9.

Step-by-step explanation:

From a random sample, we build a confidence interval, with a confidence level of x%.

The interpretation is that we are x% sure that the interval contains the true mean of the population.

In this problem:

99% confidence interval.

6 ± 3.

So between 6-3 = 3 and 6 + 3 = 9.

So we are 99% sure that the true population mean is between 3 and 9.

So the correct answer is:

A. there is a 99% probability that μ is between 3 and 9.

A low calorie dinner has 480 calories in an 9 ounce serving. What is the unit rate in simplest form? 9/48 160/3 48/9 3/160
LenaWriter [7]

Answer:Hi, the correct answer is \frac{160}{3}.

Step-by-step explanation:

 As you are being asked for rate and the importat value is the number of calories consumed. We need to simplify the fraction \frac{480 calories}{9 ounce} . Then we simplify.

Note that 480 is divisible by 3 and 9 as well. 480/3 = 160 and 9/3 = 3. Therefore, 480/9 = 160/3.
