For each of the following situations, write the null and alternative hypotheses in terms of parameter values. Example: We want to know if the proportion of up days in the stock market is 50%. Answer: Let p = the proportion of up days. $H_0$: p = 0.5 vs. $H_a$: p $\neq$ 0.5. a) Regular card customers have a default rate of 6.7%. A credit card bank wants to know if that rate is different for their Gold card customers. [Select] b) Regular card customers have been with the company for an average of 17.3 months. The credit card bank wants to know if their Gold card customers have been with the company on average the same amount of time. [Select]
