The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (computed using the same sample data) for μ = true

kenny6666 [7]

Answer:

115.3 hertz

Step-by-step explanation:

For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.

For the first interval:

$M=\frac{114.9 + 115.7}{2} \\M=115.3\ hertz$

For the second interval:

$M=\frac{114.6 + 116.0}{2} \\M=115.3\ hertz$

The sum of two numbers is 300 and the two numbers have a ratio of 20:10. Find the larger number.

Komok [63]

Step-by-step explanation:

Let the two numbers be 20x and 10x

Then by the question,

20x + 10x = 300

or, 30x = 300

or, x = 300/ 30

x = 10

Now the larger number

20x = 20* 10 = 200.

Hope it will help you :)
