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.

**Survey Analysis on Coffee Drinking Habits** Results from a survey conducted five years ago asked coffee drinkers where they typically have their first cup of coffee. The distribution was as follows: 8% while commuting, 17% at work, 70% at home, and 5% at a restaurant, coffee bar, or other location. To assess if this distribution has changed, a new survey was conducted where 581 coffee drinkers were asked about their current habits. **Table: Survey Results** | Response | Frequency | |---------------------------------|-----------| | At home | 389 | | At work | 110 | | While commuting | 55 | | Restaurant/coffee bar/other | 27 | **Analysis Question:** Based on the frequencies provided in the table, can we conclude that there has been a change in the claimed or expected distribution of locations where coffee drinkers have their first cup? Use a significance level of α = 0.05 to determine any changes. *(Adapted from USA Today)*
