Aleks [24]

Answer:

Margin of Error = 10.712

Step-by-step explanation:

The provided information is:

Sample size, n = 27

Mean $(\bar{x})$ = 250.4

Standard deviation (s) = 32.45

Degree of freedom = n - 1 = 26

Level of significance = $\alpha = 0.05$

Then, Critical Value is: $t_{\frac{\alpha}{2},df}=t_{0.025,26}=2.06$

Thus, Margin of Error:

$\begin{aligned}E &= t_{\frac{\alpha}{2},df}\times\frac{s}{\sqrt{n}}\\&=2.06\times \frac{32.45}{\sqrt{27}}\\&=2.06\times5.20\\&=10.712\end{aligned}$

MissTica

Answer:

⅛

Step-by-step explanation:

Each mark (x) on the plot presents the distance that each student jumped.

There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.

Number of students that jumped 5½ ft = 3

Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students

= 3/24

Simplify/reduce the fraction

= 1/8
