andrew11 [14]

Answer:

A)Yes they should market the wax, because it melts before 55 seconds

C) Null hypothesis: mean <55 vs. Alternative hypothesis :mean =55

D) the value is 51.33 seconds

Step-by-step explanation:

The selected samples for the champion are : 57.9, 62.9, 50.6, 50.5,48.2,47.2,50.2 and 43.1

The mean is ;

Sum =57.9 + 62.9 + 50.6 + 50.5+48.2+47.2+50.2+ 43.1 =410.6

Mean= 410.6/8 =51.33= mean

Assuming Significant =0.05 thus applying this level will give you 51.28-51.38

if specifically, the mean time to finish their standard test course should be less than 55 seconds for a former Olympic champion, then the null hypothesis is correct

Then;

Null hypothesis: mean <55

Alternative hypothesis :mean =55

12/13 divided by 3/15<br> write your answer as a simplified fraction

Agata [3.3K]

Answer:

$\frac{60}{13}$

[improper fraction]

$4 \frac{8}{13}$

[mixed fraction]

$4.\overline{615384}$

[decimal]

Explanation:

$\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b} × \frac{d}{c} = \frac{ad}{bc}$

12/13 divided by 3/15 →

$\frac{\frac{12}{13}}{\frac{3}{15}}$ →

$\frac{12}{13} × \frac{15}{3}$ →

$\frac{12}{13} × 5$ →

$\frac{60}{13}$
