Question

Write the null and alternative hypothesis which would pertain to a hypothesis test described in each scenario last year politicians average 2000 trouble hours this year with an election occurring it is expected that they will travel more hours

Answer 1

Considering the situation given, it is found that:

• The null hypothesis is $H_0: \mu = 2000$
• The alternative hypothesis is: $H_1: \mu > 2000$.

At the null hypothesis, we test if they average the same amount of trouble hours as last year, that is, of 2000 trouble hours, thus:

$H_0: \mu = 2000$

At the alternative hypothesis, we test if this amount has increased, that is:

$H_1: \mu > 2000$
