Question

do males spend more time playing online games than females? a random sample of 100 male and females was selected. let muf be the population mean number of hours spent playing online games for females and let mum be the population mean number of hours spent playing online games for males. how should we write the alternative hypothesis?

Answer 1

According to the situation given, the alternative hypothesis is:

$H_1: \mu_M - \mu_F > 0$

At the null hypothesis, it is tested if males do not spend more time playing than females, that is, the subtraction of the mean time spent playing by males by the mean time spent playing by females is of at most zero.

$H_0: \mu_M - \mu_F \leq 0$

At the alternative hypothesis, it is tested if they spend more time playing, that is, if the subtraction is positive.

$H_1: \mu_M - \mu_F > 0$
