Answer #1

Here claim is that 3/4 of all adults use internet.

So hypothesis is vs

Further it is also given that and n=3014

So test statistic is

Hence test is

Now as it is two tailed test P value is

As P value is less than alpha=0.05 we reject the null hypothesis

Hence we have sufficient evidence to support the claim that 3/4 of adults use internet.
