Answer:
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.
Step-by-step explanation:
In this test, the alternative hypothesis is:
d) Ha: μₘ- mꜰ > 0
At the null hypothesis, we test if males don't spend more time playing online games than females, that is, the subtraction of [tex]\mu_m[/tex] by [tex]m_F[/tex] is at most 0, hence:
[tex]H_0: \mu_m - m_F \leq 0[/tex]
At the alternative hypothesis, we test if males spend more time playing online games than females, that is, the subtraction of [tex]\mu_m[/tex] by [tex]m_F[/tex] is greater than 0, hence:
[tex]H_a: \mu_M - m_F > 0[/tex]
