normal hypothesis testing

[obtuse steppe]

N~(80,15²)
Ñ ~(80,15²/100)
H⁰: μ = 80
H¹ : μ >80

Observed value =83

So find p(N>=83) and compare that with the significance level

Use the sample mean when u put values in ur calc

If it's less then reject h⁰ if it's greater accept h⁰

Haven't done normal distribution in awhile so lmk if it's wrong

and somehow we're both wrong
