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
