How does one determine the null and alternative hypotheses? Give examples

Solutions

Expert Solution

solution:

claim : null hypothesis : a andriod mobile support game mean is 52

alterbate hypothesis: a andriod mobile not support game mean

this is two tail

this is the two tailed test .  

The null and alternative hypothesis is ,

H0 :   = 52

Ha :     52

claim : null hypothesis : a andriod mobile support game mean is 52

alterbate hypothesis: a andriod mobile support game less than operating system

The null and alternative hypothesis is ,

H0 :   = 52

Ha : < 52 this is left tail
