Asalesperson obtained a systematic sample of size 20 from a list of 500 clients. to do so, he randomly selected a number from 1 to 25, obtaining the number 16. he included in the sample the 16th client on the list and every 25th client thereafter. list the numbers that correspond to the 20 clients selected.

16,41,66,91,116,141,166,191,216,241,266,291,316,341,366,391,416,441,466,491

Step-by-step explanation:

The numbers that corresponds to 20 clients can be selected through systematic sampling. The samples selected through systematic sampling starting from i and then every kth unit is selected i.e. i,i+k,i+2k,...,i+(n-1)k

The numbers correspond to 20 clients selected are 16,41,66,91,116,141,166,191,216,241,266,291,316,341,366,391,416,441,466,491.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
