Question
How common are financial cost or contractual constraints associated with smartphone ownership? A survey of smartphone users found that 49% of the 18- to 29-year-olds, 37% of the 30- to 49-year-olds, 22% of the 50- to 64-year-olds, and 19% of those age 65 or older have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion: Suppose the survey was based on 200 smartphone owners in each of the four age groups: 18 to 29, 30 to 49, 50 to 64, and 65 and older. Complete parts (a) and (b) below. Use the table here to enter your data then use the TI-84 Tests.

At the 0.05 level of significance, is there evidence of a difference among the age groups in the proportion of smartphone owners who have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion?
State the null and alternative hypotheses.
H0: π1=π2=π3=π4=0
H1: At least one of the πj is not equal to zero (where j=1, 2, 3, 4)
H0: π1=π2=π3=π4
H1: π1≠π2≠π3≠π4
Ho: P1=P2=P3=P4
H1: not all P's are equal
H0: π1=π2=π3=π4=0
H1: π1≠π2≠π3≠π4≠0
The test statistic is
χ2STAT= ____
(Round to three decimal places as needed.)
p-value=____
__A__ H0. P-value is less than α... There __B__ significant evidence of a difference among the age groups in the proportion of smartphone owners who have reached the maximum amount of data they are allowed to use as part of their plan, at least on occasion.
