An educational psychologist wishes to know the mean number of words a third grader can read per minute.

Rama09 [41]

Answer: 208.

Step-by-step explanation:

The formula to find the minimum sample size is given by :-

$n= (\dfrac{z^*\times \sigma}{E})^2$ (1)

, where z* = critical z-value (two tailed).

$\sigma$ = Standard deviation ( from prior study ) and E = Margin of error.

As per given , we have

Margin of error : E= 0.29

Confidence level = 85%

Significance level = $\alpha=1-0.85=0.15$

Using z-table , the critical value (two -tailed)= $z^*=z_{\alpha/2}=z_{0.15/2}=z_{0.075}=1.439$

As per previous study , Variance = $\sigma^2=8.41$

$\sigma=\sqrt{8.41}=2.9$

Now, the required minimum sample size = $n= (\dfrac{(1.439)\times (2.9)}{0.29})^2$ [Substitute the values in formula (1)]

$n=(14.39)^2$

$n=207.0721\approx208$ [ Round to the next integer]

Hence, the minimum number of third graders that must be included in a sample = 208.

Please help!!!!!!!!!! !!

Answer:

$The ~length~ is ~9.6~ units$ ✔︎

༄❁༄❁༄❁༄❁༄

$a=8\\b=2\\c=?\\d=?\\e=5$

$Using~ Pythagorean ~theorem:$

$c^2=a^2+b^2$

$c^2=(8)^2+(2)^2$

$\sqrt{c^2} =\sqrt{68}$

$c=\sqrt{68} ~or~2\sqrt{17}$

»»---------------------►

$d^2=c^2+e^2$

$d^2=(2\sqrt{17})^2+(5)^2$

$d^2=68+25$

$\sqrt{d^2} =\sqrt{93}$

$d=\sqrt{93} ~or~9.6$

$So, your~ answer ~is ~9.6$
