Answer to Problem 10.5E
Therefore it is no enough evidence to reject the claim that the distribution of colours is as the company claimed.
Explanation of Solution
Given:
Calculation:
The expected frequencies E are the multiplication of the
The chi-square subtotals are the squared differences between the observed and expected frequencies which are divided by the expected frequency.
The value of the test-statistic would be then the sum of the chi-square subtotals:
The degrees of freedom would be the number of categories decreased by 1.
The P-value is the probability of getting the value of the test statistic, or a value more extreme. The P-value is the number in the column chi-square distribution table containing the
If the P-value is less than or equal to the significance level, then the Alternate hypothesis is accepted and Null hypothesis is rejected.
Therefore it is no enough evidence to reject the claim that the distribution of colours is as the company claimed.
