Question 10 20 pts Workers at a city owned swimming pool are investigating if the pool users accurately represent the neighborhood population. For three weeks, pool workers survey users about their neighborhood as the users sign-in. The table below provides the distribution of residents in the neighborhoods and the counts observed by pool workers. You can treat these 240 people as a random sample from the population of pool users. Neighborhood Longfellow Mosswood Piedmont Temescal Total Distribution of Residents 0.30 0 .150 .20 0.35 1.0 Observed at Pool 75 40 42 8 3 240 What can the pool workers conclude about the distribution of pool users? Compute test statistics (Select) p-value= (Select) Results: [Select]

Answer 1

The statistical software output for this problem is :

Chi-Square goodness-of-fit results: Observed: Oi Expected: Pi N DF Chi-Square P-value 240 3 1.3313492 0.7217 Observed Expected

Test statistics = 1.33135

P-value = 0.7217

We can not conclude
