 Question 202975: Determining null and alternative hypotheses A toy manufacturer claims that the mean time that its top-selling toy captures children's attention is at least 45 minutes. Suppose that we doubt this claim and we carry out a hypothesis test to see if we can refute the claim. State the null hypothesis Ho and the alternative hypothesis H1 that we would use for this test.
