The null hypothesis (H0) is typically a statement of no effect or no difference and is tested against an alternative hypothesis (HA) which reflects the claim being tested. In this case, the claim is that a typical high school student spends more than $50 a week on mobile phone calls, so the null hypothesis is that the mean (μ) is equal to 50, and the alternative hypothesis is that the mean is greater than 50.
