Please help me I will give you extra points and the brain thing
vovangra [49]

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

To create a confidence interval from a bootstrap distribution using percentiles, we keep the middle values and chop off a certai
Nataliya [291]

Answer:

a

 \frac{\alpha }{2}  =  2.5 \%

b

  N  = 25

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    

      \alpha = (100 - 95 ) \%

=>   \alpha = 0.05

Generally the percentage of values that must be chopped off from each tail  for a 95% confidence interval is mathematically evaluated as

      \frac{\alpha }{2}  =  \frac{0.05}{2}  =  0.025 = 2.5 \%

=>    \frac{\alpha }{2}  =  2.5 \%

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

      N  =  1000 *  \frac{\alpha }{2}

=>   N  =  1000 *  0.025

=>   N  = 25
