Complete Question

A manufacturer of banana chips would like to know whether its bag filing machine works correctly at the 445 gram setting is there sufficient evidence at the 0.01 level that the bags are underfilled? Assume the population is normally distributed State the null and alternative hypotheses for the above scenario

Answer:


H_o=\mu=445g


H_a=\mu<445g

Explanation:

From the question we are told that:

Mass
M=445g

Significance level
\alpha=0.01

Generally the Null and Alternative Hypothesis is


H_o=\mu=445g

i.e The bags are not under filled


H_a=\mu<445g

i.e The bags are under filled
