Assume that all grade-point averages are to be standardized on a scale between 0 and 4. How many grade-point averages must be

guapka [62]

Answer:

a) The required sample size n= 55011,57025

b) The sample size is not practical, because that size is extremely large and would be very costly to collect, normally the size have to be significant but no to large to avoid cost unnecessary

Step-by-step explanation:

Range

$σ = \frac{4-0}{4} = 1$

$E = 0,011 \\c= 99 %\\$ ⇒ 0,99

Sample size can be determinate using equation:

$n=(\frac{Z_{\alpha /2 * σ} }{E})^{2}$

Using confidence level desired 99% $Z_{\alpha /2}$ = 2,58

Table used :

<em>Confidence $Z_{\alpha/2 }$ </em>

<em> 90 % 1,60</em>

<em> 95 % 1,96</em>

<em> </em><em> 99 % 2,58</em>

<em> 99,9 % 3,291</em>

So replacing:

$n=(\frac{2,58 * 1 }{0,011})^{2}$

$n= 234,5454545^{2} \\n=55011,57025$
