A new Contingency Analysis was run with a smaller sample

what would your conclusion be with α=0.10 ?

Another sample (regarding 24 students), was considered to run the same test, with the same variables. The test statistic value was computed and the corresponding p-value was found to be 0.05.

The expected number of young students using Netflix more than 10 hours per week (if Ho is true) is 

Check this ANOVA

With α=0.05, what would your main conclusions be ?

Check this ANOVA

Willingness to pay for Netflix streaming service (WP) is considered to be Age dependent. Maybe this belief is not correct!

To investigate this we would run a statistical test in which Ho is

Regarding GPA, this H1: μ<16 was considered. The p-value

As you know, with the provided information, we are not able to run a one-sided test regarding Income μ.
