There's not adequate prove to conclude that there's a contrast within the color between title brand Gummy bears and store-brand Gummy bears

Step by step solution

Given information

We have been given the color, name and brand for different gummy bears.

Explanation

Null Hypothesis; Ho - there's no distinction within the color between name-brand Gummy bears and store-brand Gummy bears Alternative Theory; Ha - there's a contrast in the color between name-brand Gummy bears and store brand Gummy bears We will run one-way ANOVA test to see in the event that there exists any contrast between the two.

The $f$ ratio value is $3.08263$ .The $p - v a l u e$ is $117204$ . The result is not significant at $p < . 05$

$F$ -statistics $= 3.08263$

$p - v a l u e = 0.1172$

Since $p - v a l u e$ $>$ significance value which means it is insignificant and we fail to reject the null hypothesis
