Answer:

The null hypothesis is $H_{0} = 4.3$ .

The alternate hypothesis is $H_{a} > 4.3$

Step-by-step explanation:

Null hypothesis:

The previously report, the known value.

Alternate hypothesis:

What is questioned(higher, lower, different,...) of the null hypothesis

Previously, an organization reported that teenagers spent an average of 4.3 hours per week, on average, on the phone.

This means that the null hypothesis is $H_{0} = 4.3$ .

The organization thinks that, currently, the mean is higher.

That is, higher than 4.3. So

The alternate hypothesis is $H_{a} > 4.3$
