Question

claim: the average weight of males is greater than 53 kg. ten male students were selected to test this claim.we also set our $\alpha=0.01$, $\bar{x}=51$, $s = 4.74$, $n = 10$, $df=10 - 1=9$ step 1: what is the null hypothesis? $h_0:\mu\leq53$ $h_0:\mu>53$ $h_0:\mu = 53$ $h_0:\mu\
eq53$

Explanation:

In hypothesis testing, the null hypothesis ($H_0$) is a statement of no effect or no difference. The claim is that the average weight of males is greater than 53 kg (which would be the alternative hypothesis $H_1:\mu > 53$). The null hypothesis is the opposite or a statement that includes equality for the parameter being tested. When testing a claim about a population mean ($\mu$) where the alternative is one - sided ($\mu>53$), the null hypothesis takes the form that includes the value in the alternative hypothesis in a non - alternative way. Here, it is $H_0:\mu\leq53$ because we are comparing against the claim $\mu > 53$.

Answer:

$H_0:\mu\leq53$
