State the null and alternative hypotheses for the above scenario.

Answer:

The null hypothesis is
`H_o : p \le 0.411`

The alternative hypothesis is
`H_a : \mu > 0.41`

Explanation:

From the question we are told that

The proportion is
`p = 0.41`

Generally the null hypothesis is
`H_o : p \le 0.411`

The above condition represents the null hypothesis because it contains and equality in its condition

The alternative hypothesis is
`H_a : \mu > 0.41`
