Question

a company claims that its tablet computers have an average recharge time of 3 hours. in a random sample of these computers, the average recharge time is 2.5 hours. you suspect that the average recharge time might be less than what the company claims. let μ represent the average time, in hours, needed to recharge the companys tablet computers. what is the null hypothesis, h₀, for this situation? μ<3 μ = 3 μ = 2.5 μ>2.5

Explanation:

The null hypothesis represents the status - quo or the claim that is initially assumed to be true. Here, the company claims an average recharge time of 3 hours. So the null hypothesis is that the population mean $\mu$ is equal to the claimed value.

Answer:

$\mu = 3$
