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
Answer:
37 cars per hour
Step-by-step explanation:
185 cars = 5 hrs
divide 185 by 5
Answer:
Hello, the answer is $7.50 dollars.
5% is 0.5.
You multiply $150 by 0.5, then you get $7.50 dollars as the answer.
Ex. if it was 18h + 27a the answer will be 9(2h + 3a) because 9 is the GCF and if u multiply the 9 by 2h it will be 18h then multiply 9 by 3a it will be 27 and that will give you the answer of 18h + 27a in Distributive Property
Answer: Kicker C, kicker B, and then kicker A
Step-by-step explanation:
divide the field goals made by field goals attempted to get the success rate. A = 12 / 14 = 0.857 B = 15 / 18 = 0.83 C = 19 / 24 = 0.79
0.79 < 0.83 < 0.857
