Answer:
2.5%
Step-by-step explanation:
The percentage of people taking the test who are above 698 is ___%
Empirical rule formula states:
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ
From the question, we have:
Mean of 514 and a Standard deviation of 92
Hence:
μ ± xσ
514 ± 92x = 698
514 + 92x = 698
92x = 698 - 514
92x = 184
x = 184/92
x = 2
Hence, the data is correct and it is 2 standard deviation from the mean. Therefore, 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
The question is asking us to find the percentage of people taking the test who are above 698 is calculated as:
100 - 95% /2
= 5/2
= 2.5%
The percentage of people taking the test who are above 698 is 2.5%
The probability that all men will be interviewed first is; 1/55
<h3>How to find probability combination?</h3>
To solve this question we will make use of the probability combination formula which is;
nCr = n!/(r! * (n - r)!)
Thus, since we want to find the probability that all men will be interviewed first, then we will use the formula;
3(3!)/((11C1) * (10C1) * (9C1)) = 18/990
Simplifying that fraction gives us; 1/55
