Do males spend more time playing online games than females? A random sample of 100 males and females was selected. Let mꜰ be the
population mean number of hours spent playing online games for females and let μₘ be the population mean number of hours spent playing online games for males. How should we write the alternative hypothesis?
a) Ha: μₘ - mꜰ ≠ 0
b) Ha: μₘ- mꜰ = 0
c) Ha: μₘ- mꜰ < 0
d) Ha: μₘ- mꜰ > 0
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.
First let as solve all unit pirce whistles 21.25 / 25 = $ 0.85 per unit 36 / 50 = $ 0.72 per unit 60 / 80 = $ 0.75 per unit kazoos 10 / 25 = $ 0.4 per unit 18.50 / 50 = $ 0.37 per unit 27.20 / 80 = $ 0.34 per unit a.) $ 0.85 - $ 0.72 = $ 0.13 b.) 10 / 25 = $ 0.4 per unit c.) he must order 80 kazoos she should order
