SECOND: DIFFErS FROM EXPECTED
INDEPENDENT OF AGE
IS THE SAME AS EXPECTED
IS DEPENDENT ON AGE
IS UNIFORMLY DISTRIBUTED
You are investigating the relationship between the ages of adults and what aspect of career development they consider to be the most important. You rando ly collect the data shown in the contingency table. At o 0.01, is there enough evidence to conclude that age is related to which aspect of career development is considered to be most important? Perform the chi-square independence test by completing parts (a) through (e) below. Career development aspect Age Learning new skills Pay increases Career path 18-26 years 31 23 23 27-41 years 30 32 42-62 years (a) Identify the claim and state Ho and Ha Ho: The aspect of career development that is considered to be most important Ha: The aspect of career development that is considered to be most important is independent of age Which hypothesis is the claim? is dependent on age. is the same as expected. O Alternative hypothesis O ull hypothesis differs from the expected. b) Determine the degrees of freedom find the critical value and identi fy the rei is uniformly distributed.Explanation / Answer
a)h0:independent of age
ha:dependent of age
b)df=(3-1)*(3-1)=4
x^2 value 3.7418
x0^2 value at df=4 is at 0.01 significance level 13.276
x^2<x0^2
The chi-square statistic is 3.7418. The p-value is .442082. The result is not significant at p < .01.
reject null hypothesis
