Answer:
53.8°
Step-by-step explanation:
Use cosine law
67² = 72² + 76² - 2(72)(76)cosX
cosX = 719/1216
X = 53.75190075
Answer:
A. n = 5
Step-by-step explanation:
S = n² + n
When S = 30:
n² + n = 30
Subtract 30 from both sides: n² + n - 30 = 0
Factorize: (n - 5)(n + 6) = 0
Therefore n = 5 or -6
As n > 2, then n = 5 only

Answer:
a

b

Step-by-step explanation:
From the question we are told that
The number of bootstrap samples is n = 1000
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally the percentage of values that must be chopped off from each tail for a 95% confidence interval is mathematically evaluated as

=> 
Generally the number of the bootstrap sample that must be chopped off to produce a 95% confidence interval is

=> 
=>
