Answer:
Hence, the minimum required sample size (n) should be = 1692
Step-by-step explanation:
Solution:-
- The estimation error, E = 2%
- The confidence level, CI = 90 %
- Since the proportion of the positive lab tests for prostate cancer are actually proven correct through subsequent biopsy are unknown we will assume the corresponding proportion to be p = 0.58
- The required sample size is a function of confidence value and error of estimation (E):
Where,
- The critical value of the confidence level = 90% would be:
significance level ( α ) = 1 - CI = 1 - 0.90 = 0.1
Z-critical = Z_α/2 = Z_0.05 = 1.645
- The required sample size (n) can be calculated:
- Hence, the minimum required sample size (n) should be = 1692
The correct answer is C) 6
Add and convert it into a mixed fraction
Answer:
6 cells
Step-by-step explanation:
Cell A = 1 hour to complete cycle and produce 2 cells
Number of cycles completed on 6 hours = 6 cycles
Number of cell produced = 2 * number of completed cycles = 2 * 6 = 12 cells
Cell B = 2 hours to complete a cycle ; 2 cells produced per cycle
Number of cells produced after 6 hours :
Number of cycles in 6 hours = 6/2 = 3 cycles
Number of cells produced = 3 * 2 = 6 cells
Difference in cells produced : (12 - 6) = 6 cells
2) y= 18
4) w= 8, area= 96
