Answer:
[tex]\mu [/tex] = 10.1163 kg
Step-by-step explanation:
given data
σ = 0.05
x = 10
so we know here probability of x is 0.1 that is less than 10
so here Z is -2.326 by the standard table
we have here 1% to left when Z is - 2.326
now we apply relation between Z and x that is
Z = [tex]\frac{x -\mu}{\sigma }[/tex] .........1
put here value
-2.326 = [tex]\frac{10 - \mu }{0.05}[/tex]
[tex]\mu [/tex] = 10.1163 kg
