Question

A 37 bag sample had a mean of 421 grams. Assume the population standard deviation is known to be 29. A level of significance of 0.05 will be used. State the null and alternative hypothesis.

Answer 1

Answer:
`H_0:\mu=421`

`H_a : \mu\\eq421`

Explanation:

• A null hypothesis is a type of hypothesis that is used in statistics that assumes there is no difference between particular characteristics of a population wheres the alternative hypothesis shows that there is a difference.

Given: A 37 bag sample had a mean of 421 grams.

Let
`\mu` be the population mean.

Then, the null hypothesis would be:

`H_0:\mu=421`

whereas the alternative hypothesis would be:

`H_a : \mu\\eq421`
