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

lord [1]

The amount of energy waste, in terms of hours which a 60-watt light bulb would remain on, is 61.6 hours then the correct option is B.

<h3>What are ratio and proportion?</h3>

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Marco leaves the bathroom faucet running for 22 minutes while he gets ready in the morning.

Running the faucet for 5 minutes wastes the same amount of energy as leaving a 60-watt light bulb on for 14 hours.

Then we have

\begin{aligned} \dfrac{5\ minutes}{14 \ hours } &=\dfrac{1\ minute }{x \ hours}\\\\x &= 2.8  \ hours \end{aligned}

So, the rate is 2.8 hours per minute.

Since macro leaves the bathroom faucet running for 22 minutes. Then the waste of energy is leaving a 60-watt light bulb will be

→22 minutes × 2.8 hours/minute = 61.6 hours.

More about the ratio and the proportion link is given below.
