A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting. It is
lord [1]

Answer:

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447 gram setting.

H_0:\mu = 447\\H_a:\mu\neq 447

Mean = \mu = 447\\s = 21\\x = 443

n = 19

Since n < 30 , so we will use t test

t=\frac{x-\mu}{\frac{s}{\sqrt{n}}}

Substitute the values :

t=\frac{443-447}{\frac{21}{\sqrt{19}}}

t=−0.8302

t calculated = -0.830

degree of freedom = n-1 = 19-1 = 18

A level of significance=α=0.025

t_{(df,\frac{\alpha}{2})}=2.093

t critical = 2.093

t calculated < t critical

So, We failed to reject null hypothesis

Decision rule  -0.830< 2.093 So, We failed to reject null hypothesis
