Suppose the manager of a restaurant in a commercial building has determined that the proportion of customers who drink tea is 24
BartSMP [9]

Answer:

0.427

Step-by-step explanation:

Standard error for the sampling distribution refers to the standard deviation of the samples taken from a population. The standard error equals the standard deviation divided by the square root of the sample size

The probability of customers who drink tea (p) = 24% = 0.24, the sample size of customers (n) = 300.

Standard error = \frac{\sigma}{\sqrt{n} } where σ is the standard deviation.

\sigma=\sqrt{np(1-p)}

Standard error = \frac{\sigma}{\sqrt{n} }= \frac{\sqrt{np(1-p)} }{\sqrt{n} } =\sqrt{\frac{np(1-p)}{n} } =\sqrt{p(1-p)}=\sqrt{0.24(1-0.24)}  =0.427

Which do you prefer: leaving √5 in radical form, or converting it to a decimal? Why? When would it be useful to use each?
Goshia [24]

Answer:

Leaving as a radical form

Why?

Because that's the whole value if you convert it to a decimal you cannot write all the numbers, and in the radical form it has all the numbers

It would be useful when we are working with equations for example the quadratic equation, if you get that x=√5, you would want the exact value. And there are more useful
