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

Nataliya [291]

Answer:

$\frac{\alpha }{2} = 2.5 \%$

$N = 25$

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

$N = 1000 * \frac{\alpha }{2}$

=> $N = 1000 * 0.025$

=> $N = 25$

If 75% is £60 what is the full cost

fgiga [73]

If you would like to know what is the full cost if 75% is £60, you can calculate this using the following steps:

75% of x = £60
75% * x = £60
75/100 * x = 60 /*100/75
x = 60 * 100 / 75
x = £80

Result: The full cost is £80.
