Step-by-step explanation:
According to the Question,
Given, The human resource department at a certain company wants to conduct a survey regarding worker benefits. The department has an alphabetical list of all 4247 employees at the company and wants to conduct a systematic sample of size 40.
a). Thus, the Required Value of K is 4247/40 = 106.175 ≈ 106
b). The individuals who will be administered the survey. Randomly select a number from 1 to k. Suppose that we randomly select 19. Starting with the first individual selected, the individuals in the survey will be
- 19
- (19+106) = 125
- (125+106) = 231
- 337
- 443
- 549
- 655
- 761

To find how much 43% of 210 is, we do a part/whole=percent/100, so a/210=57/100, 210•57=11970/100=119.70, so that means that 210-119.70=90.30, so 210+90.30=300.30 as the final cost
