Is a measure of 25 inches​ "far away" from a mean of 16 ​inches? As someone with knowledge of​ statistics, you answer​ "it depen

ds" and request the standard deviation of the underlying data. ​(a) Suppose the data come from a sample whose standard deviation is 3 inches. How many standard deviations is 25 inches from 16 ​inches? ​(b) Is 25 inches far away from a mean of 16 ​inches? ​(c) Suppose the standard deviation of the underlying data is 7 inches.

Answer:

a) 25 is 3 standard deviation from the mean

b) Is far away from the mean, only 0,3 % away from the right tail

c) 25 is pretty close to the mean (just a little farther from 1 standard deviation)

Step-by-step explanation:

We have a Normal Distribution with mean 16 in.

Case a) we also have a standard deviation of 3 inches

3* 3 = 9  

16 (the mean) plus 3*σ  equal 25 in. the evaluated value, then the value is 3 standard deviation from the mean

Case b) 25 is in the range of 99,7 % of all value, we can say that value is far away from the mean, considering that is only 0,3 % away from the right tail

Case c) If the standard deviation is 7 then

mean + 1*σ  =  16 + 7 =23

25> 23

25 is pretty close to the mean only something more than 1 standard deviation

maw [93]

Answer:

Ф = ------------ = 7/5 radians

Step-by-step explanation:

"e" is inappropriate format here.  Use Ф or α or similiar character for central angle.

Here, (arc length) = (radius)(central angle),  or  s = rФ, and so:

(central angle) = Ф = (arc length) / (radius)

                     7 ft

Here, Ф = ------------ = 7/5 radians

                    5 ft

The sum of three consecutive odd numbers is one hundred and eleven. what is the smallest of the three numbers?
Firdavs [7]
35,37,39
111 divided by 3 is 37...so that is the middle number.  Two below it is 35 and 2 above it is 39 and all three would add up to 111.  So 35 is the lowest.
