Answer:
The probability that all 14 bits are 1s = 0.000061
Step-by-step explanation:
Probability that a bit is 1 is p = 0.5
Probability that a bit isn't 1 is q = 1 - 0.5 = 0.5
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = 14
x = Number of successes required = 14
p = probability of success = 0.5
q = probability of failure = 0.5
P(X = 14) = ¹⁴C₁₄ (0.5)¹⁴ (0.5)¹⁴⁻¹⁴
P(X = 14) = ¹⁴C₁₄ (0.5)¹⁴ (0.5)⁰
P(X = 14) = 1 (0.000061)(1) = 0.000061
Answer:
38.65 im pretty sure
Step-by-step explanation:
Part A you would use 200-L ( since you have 400 feet total 200 feet would equal length plus width)
Part B 200 - 80 = 120
Part C 200-90 = 110
area = 90 x 110 = 9900 square feet
Answer:
The test statistic is 
Step-by-step explanation:
We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.
At the null hypothesis, we test if the proportion is 80%, that is:
At the alternate hypothesis, we test if the proportion is more than 80%, that is:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation and n is the size of the sample.
80% is tested at the null hypothesis:
This means that 
A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.
This means that 
The test statistic is
The test statistic is
9,7,5,3,.................
