For each problem, a) identify the null and alternative hypothesis, b) find the critical value and dentify the rejection region, c) calculate chi-square, d) decide whether to accept or reject the null hypothesis, e) write an APA format results statement. ONE: Results from a survey five years ago asking where coffee drinkers typically drink their first cup of coffee were as follows: 8% while commuting, 17% at work, 70% at home, and 5% at a restaurant/coffee bar or other location. To determine whether this distribution has changed, you randomly select 581 coffee drinkers and ask each where they typically drink their first cup of coffee. Based on the results provided in the table, can you conclude that there has been a change in the claimed or expected distribution of locations? Use a = 0.05.
