Sagot :
Answer:
0.15401
Step-by-step explanation:
Given that test statistic = 3.7408
From the question, we could deduce that, this is scenario could be analysed A ONE - WAY analysis of Variance method as it has one independent variable, Age subdivided into 3 levels
The test statistic value obtained is the Chisquare (χ²) value, which equals 3.7408
To Obtain the requested Pvalue, we need the degree of freedom, which is :
(Number of columns - 1) * (number of rows - 1)
Number of candidates = 2
Number of levels = 3
Hence,
Degree of freedom = (3 - 1) * (2 - 1) = 2 * 1 = 2
Using the Chisquare Pvalue calculator or distribution table :
χ²;3.7408, 2 = 0.154062
Pvalue = 0.1541
The probability that the observed responses is 0.15401
Given that test statistic = 3.7408
From the given , we can conclude that, this is scenario could be analysed a one -way analysis of variance method as it has one independent variable,
Age subdivided into 3 levels
The test statistic value obtained is the Chi-square (χ²) value,
Chi-square (χ²) value= 3.7408
What is the formula for degree of freedom?
(Number of columns - 1) * (number of rows - 1)
Number of candidates = 2
Number of levels = 3
Degree of freedom = (3 - 1) * (2 - 1)
= 2 * 1
= 2
Using the Chisquare Pvalue calculator or distribution table :χ²;
3.7408, 2 = 0.154062
P-value = 0.1541
Therefore,the probability that the observed responses would be as far or farther from the expected responses if there is no association between age- group and preference is 0.1541.
