Answer:

y=32

Step-by-step explanation:

The relationship between the value of x and y is multiplying by 8, therefore when x equals 4, y equals 32.

Answer:

32

Step-by-step explanation:

simplify 24/3 = 8 then (24 / 4) *  (2) = 48/8 = 6  = 6/8 = 3/4    we need to divide 24 by 3/4  = 32   or show 24  * 3/4   = 32     32 * 3/4 =  24

David Barnes and his fiancée Valerie Shah are visiting Hawaii. At the Hawaiian Cultural Center in Honolulu, they are told that
balandron [24]

Using the hypergeometric distribution, it is found that there is a 0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

The people are chosen without replacement from the sample, hence the <em>hypergeometric distribution </em>is used to solve this question.

<h3>What is the hypergeometric distribution formula?</h3>

The formula is:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • N is the size of the population.
  • n is the size of the sample.
  • k is the total number of desired outcomes.

In this problem:

  • There is a total of 18 people, hence N = 18.
  • 2 people will be chosen, hence n = 2.
  • David and Valerie corresponds to 2 people, hence k = 2.

The probability that both get picked is P(X = 2), hence:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}

P(X = 2) = h(2,18,2,2) = \frac{C_{2,2}C_{16,0}}{C_{18,2}} = 0.0065

0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

If 95% and 98% confidence intervals were calculated from the same sample data in order to estimate the true cost of an appliance
damaskus [11]

Answer:

D) The z-statistics would be different.

Step-by-step explanation:

Confidence Interval can be calculated using M±ME where

  • M is the sample mean
  • ME is the margin of error from the mean

An margin of error (ME) from the mean can be calculated using the formula

ME=\frac{z*s}{\sqrt{N} } where

  • z is the corresponding z-statistic in the given confidence level
  • s is the population standard deviation
  • N is the sample size

If 95% and 98% confidence intervals were calculated from the same sample data, then M, s and N are same.

\frac{s}{\sqrt{N} } is called standard error. Since s and N are same the standard errors would also be same.

But, two tailed z-statistic for 95% confidence level is ≈1.96 where for 98% it is ≈2.33
