Answer:
H0: u = 0.25 (Null)
Ha: u > 0.25 (Alternate)
Step-by-step explanation:
Hypothesis is written following the rules below:
i) 2 hypotheses are formed in a way that complement of one is claim in the other.
ii) H₀ - the null hypothesis , is the boring hypothesis which claims that things are expected
iii) H₁ -the alternative hypothesis states a claim against null. It always contain the strict inequality signs : less than sign (<), greater than sign (>)and not equal to sign (≠).
Here, we are testing if the mean is less than 0.25 inch
We thus have :
H₀ : u = 0.25 as the null hypothesis and
H₁ : u > 0.25 as the alternative hypothesis
The null hypothesis is the average hair growth is a quarter inches per month. [tex]H_{0} = \frac{1}{4}[/tex] and the alternative hypothesis is the average hair growth is greater than a quarter inches per month.[tex]H_{1}[/tex] > [tex]\frac{1}{4}[/tex].
A hypothesis is a temporary explanation for a phenomena. This explanation can either be proved or disproved by carrying out tests or
The null hypothesis states that there is no relationship between the population parameters. The alternative hypothesis states that there is a relationship between the population parameters.
