An experiment compares the taste of instant coffee versus fresh brewed. Each subject tastes two unmarked cups of coffee – in random order – and states which he or she prefers. Of the 50 who participate, 19 (or 38%) prefer the instant coffee while the remaining 31 (or 62%) prefer the fresh brewed. Let pdenote the proportion of the population who prefer fresh-brewed over instant. We wish to test if people prefer fresh-brewed over instant. Which of the following are the appropriate null and alternative hypotheses? Hint: if people cannot tell the difference between fresh brewed and instant, what would that make the value of p be? The null hypothesis is H0: ["", "", "", ""] The alternative hypothesis is Ha:
