Which of the following conditions must be met in order to make a statistical inference about a population based on a sample
klasskru [66]

Answer:

For this case if we want to conclude that  the sample does not come from a normally distributed population we need to satisfy the condition that the sample size would be large enough in order to use the central limit theoream and approximate the sample mean with the following distribution:

\bar X \sim (\mu, \frac{\sigma}{\sqrt{n}})

For this case the condition required in order to consider a sample size large is that n>30, then the best solution would be:

n>= 30

natima [27]

Answer:

<h2>4</h2>

Option A is the right option.

solution,

∆ABC~∆EDC

\frac{bc}{cd}  =  \frac{ac}{ec}  \\  \:

putting the values,

\frac{20 - x}{x}  =  \frac{20}{5}  \\  or \: 5(20 - x) = 20x(cross \: multiplication) \\ or \: 100 - 5x = 20x \\ or \:  - 5x - 20x =  - 100 \\ or \:  \:  - 25x =  - 100 \\  \: or \: x =  \frac{ - 100}{ - 25}  \\ x = 4

Hope this helps..

Good luck on your assignment..
