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 formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04
