(a)
To Calculate: the chi-square statistic of observed counts for a bag with 60 candies that result in a P-value between 0.01 and 0.05.
(a)
Answer to Problem 10.10E
Explanation of Solution
Given:
Formula used:
Calculation:
The previous part solved that the P-value is less than 0.05 if the
The previous part solved the P-value is less than 0.01 if the
Therefore require to find a set of observations such that the chi-square statistic is between 9.49 and 13.28.
The expected frequencies
For example, Assume the observe value be for the flowers be: 7 for 3 flowers each and 17 for 3 flowers each.
7, 7, 7, 17, 17, 17
The value of the test-statistic is
(b)
To Explain: the conclusion drawn in this case.
(b)
Answer to Problem 10.10E
Explanation of Solution
Given:
If the P-value is less than or equal to the significance level, then the null hypothesis is rejected:
Therefore it would reject the flavour bend contains 20 percent of each flavour at the
