Consider the following to answer the question(s) below: A local cell phone provider wants to determine if the use of text messaging is independent of age. The following data has been collected from a random sample of customers. -At α = 0.05, A) we reject the null hypothesis. There is no evidence that use of text messaging is independent of age. We and can conclude that there is an association between age and the use of text messaging. B) we fail to reject the null hypothesis. C) we fail to reject the null alternative hypothesis and can conclude that use of text messaging is independent of age. D) as the P-value χcr2 = 5.991, we support the null hypothesis and can conclude that age and use of text messaging are not related.

Question

Consider the following to answer the question(s) below:
A local cell phone provider wants to determine if the use of text messaging is independent of age. The following data has been collected from a random sample of customers.
 
-At α = 0.05,
A) we reject the null hypothesis. There is no evidence that use of text messaging is independent of age. We and can conclude that there is an association between age and the use of text messaging. 
B) we fail to reject the null hypothesis. 
C) we fail to reject the null alternative hypothesis and can conclude that use of text messaging is independent of age. 
D) as the P-value < .0001 is very low, We reject the null hypothesis.there is no association between age and the use of text messaging. 
E) since χ2 = 92.2095 > χcr2 = 5.991, we support the null hypothesis and can conclude that age and use of text messaging are not related.

At α = 0.05, since the p-value is less than 0.05, we reject the null hypothesis. This means there is evidence of association between age and the use of text messaging. Therefore, choice A is the best option.
