Jlenok [28]

Answer:

\sf x = 7.8

explanation:

\sf a^2 + b^2 = c^2

\hookrightarrow \sf 9.5^2 + x^2 = 12.3^2

\hookrightarrow \sf x^2 = 12.3^2 - 9.5^2

\sf \hookrightarrow x^2 = 151.29 - 90.25

\hookrightarrow \sf x^2 = 61.04

\hookrightarrow \sf x = \sqrt{61.04}

\hookrightarrow \sf x = 7.8

Flauer [41]

Answer:

H0 : //μA = μB = μC

Step-by-step explanation:

Given the data:

Treatment | Observation

A | 20 | 30 | 25 | 33

B | 22 | 26 | 20 | 28

C | 40 | 30 | 28 | 22

To test whether there is a difference between the group means of a sample ; the ANOVA test is employed ;

The appropriate hypothesis test:

The alternative hypothesis will habour the notion that there is a difference in sample means while the alternative will be opposite, that is, no difference exists in the sample means for the three treatments :

Null hypothesis ; H0 : μA = μB = μC ;

The alternative hypothesis, takes the opposite of the null ;

H1 : μA ≠ μB ≠ μC (this means that the mean values of the treatments are not the same

The null hypothesis will
