Answer 1

`H0: mu = 8.9 fl oz.\\\\`

`Ha: mu ≠8.9 fluid oz`

Explanation:

Given that A perfume company claims that the mean weight of ther new perfume is at least 8.9 fluid oz

For testing this claim, in Statistics we perform a certain measures called hypothesis testing.

For this first step is to create null and alternate hypothesis.

Normally null hypothesis would have some statistic = something

Here we want to test the mean weight of perfume

Hence null hypothesis would be

H0: mu = 8.9 fl oz.

Alternate hypothesis would be opposite of this claim

i.e.

Ha: mu ≠8.9 fluid oz

Hence answer is

`H0: mu = 8.9 fl oz.\\\\`

`Ha: mu ≠8.9 fluid oz`
