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) If the breadth of rectangle in one-third of its length and perimeter is 80 cm, find the length and breadth of rectangle. ​
Gwar [14]

Answer:

Length = 30m and Breadth = 10m  

Step-by-step explanation:  

Given that :  

Perimeter = 80 m ;  

Breadth = 1/3 of Length ; Length = l  

We know that :  

Perimeter of rectangle = 2 ( L + B ).  

80 = 2 ( L + 1/3 L )  

80/2 = 4/3 L.  

40 = 4/3 L  

3/4 × 40 = L.  

3 × 10 = L.  

L = 30m.  

Breadth = 1/3 of Length.  

Breadth = 1/3 × 30.  

Breadth = 10m.
