Also we knew the relationship between teenagers and “Apple” products.

The questionnaire set was very simple, thus a significance level of 5% which is strong evidence was chosen. A two-tail hypothesis test was conducted as it is required to find out whether there is different in the population proportion only.

In the test, we just used the question 2: Are you using I Phone? It is because we needed to test the different to boys and girls using. In the bar chart, we used the proportion to show the data, because it can be eased to understand the data.


I.e. (1) =question 1 answer; (2) =question 2 answer

Using:

“Are you using I Phone? (Boys)” (A1)
Sample size (n1): 80
“Are you using I Phone? (Girls)” (A2)
Sample size (n2): 80

Step:

1) H0 : A1 = A2
H1: A1≠A2

2) A5% significance is adopted. So. ∝=0.05,that z= ±1.96

3) Since, we have two sample, so we use the test statistic is

z=p1-p2pc(1-pc)n1+pc(1-pc)n2

We have,

P1 =0.45; p2 =0.64
Pc = 80×0.45+80×0.6480+80 = 0.545

So,

z= 0.45-0.640.545(1-0.545)0.45+0.545(1-0.545)0.64
= -0.190.24880+0.24880
= -2.413

Since -2.413<-1.96 , so we reject H0. It means there is difference of boys and girls to using IPhone.
