Why is 1/6 greater than 1/8 but less than 1/3
VladimirAG [237]

So first thing we have to realise is that we have to make them have equal denominators. So,

\frac{1}{6} =  \frac{4}{24}  \\ \\   \frac{1}{8} =  \frac{3}{24}  \\  \\  \frac{1}{3} =  \frac{8}{24}.

Now order the fractions....so,

\frac{1}{3} = \frac{8}{24}  \\  \\ \frac{1}{6} = \frac{4}{24} \\ \\ \frac{1}{8} = \frac{3}{24}

Now we can see why \frac{1}{6} is greater than \frac{1}{8} but less than \frac{1}{3}

Answer:

p value = 0.302

Step-by-step explanation:

Given that all cars can be classified into one of four​ groups: the​ subcompact, the​ compact, the​ midsize, and the​ full-size. There are five cars in each group. Head injury data​ (in hic) for the dummies in the​ driver's seat are listed below.

H_0: All cars have same mean values

H_a: atleast two cars have different mean values

(Two tailed anova test)

Anova: Single Factor

Since p value of 0.302 is greater than 0.05 significance level we accept null hypothesis.

p value = 0.302
