Answer:

the greater the precision the smaller the standard deviation

there is no relationship between standard deviation and accuracy

Step-by-step explanation:

The standard deviation of a set measures how close the measures of this set are, that is, how precise they are.

The lesser the standard deviation is, the higher the precision is.

So the correct answer is:

the greater the precision the smaller the standard deviation

Accuracy is how close a measurement comes from the correct value. There is no relation between standard deviation and accuracy.

So:

there is no relationship between standard deviation and accuracy

Answer:

30.5 ; 49 ; 27 ; 50 ; 45

Step-by-step explanation:

Determine the first and third quartiles. Determine the second decile and the eighth decile. Determine the 67th percentile

Given the ordered data :

13 13 13 20 26 27 29 32 34 34 35 35 36 37 38 41 41 41 42 44 46 47 48 50 53 55 56 62 67 82

Sample size, n = 30

The first quartile ;Q1

Q1 = 1/4(n+1)th term

Q1 = 31/4 = 7.75th term

Q1 = (29+32)/2

Q1 = 30.5

Q3 ;

Q3 = 3/4(n+1)th term

Q3 = 3(31)/4 = 23.25 th term

Q3 = (48 + 50) /2 = 49

2nd decile :

0.2 * (nth term

0.2 * 30 = 6th term = 27

8th decile :

0.8 * 30 = 24 th term

= 50

67th percentile :

0.67 * (n+1)th term

0.67 * 31 = 20.77

= (44 + 46) / 2

= 45

Alchen [17]
The sum will be: 

sigma(i = 1 to infinity, 30*(2/5)^i) 

->\lim_{i \to \infty}  \frac{30(1-   \frac{2}{5}^{i} )}{ \frac{3}{5} }

Which is equal to 30/(3/5) = 50

True or False: The relation {(3, 2), (1, 2), (7, –5), (11, 6), (17, –4), (13, 8)} is a function.
8090 [49]

Answer:

False

Step-by-step explanation:

This is because if you have a function which is Y=2x-4 , then trying to give an example using the given points which (3,2) , here we will have Y=2 upon replacing 3 in the function cause 3 is the value of x and vice versa if we have 2 as the value of Y then x will be 3 . However,if we get the (1,2) the answer for Y will be -2 which is different from the one we have in the question hence this concludes false
