5. Joan asked 30 randomly selected adult restaurant customers about their choice of beverages. Eighteen customers said coffee is their favorite beverage. If the restaurant serves 200 adult customers per day, estimate the number who will choose coffee to drink.
A. 100
B. 110
C. 120
D. 130
The proportion of customers who said coffee is their favorite beverage is:
p̂ = 18/30 = 0.6
We can use this proportion to estimate the number who will choose coffee to drink out of 200 customers:
n̂ = 0.6 x 200 = 120
Therefore, the estimated number who will choose coffee to drink is 120.
The answer is (C) 120.
The table shows Christin’s best javelin throws each year. Make a scatter plot that represents the given data.
Year 1997 1998 1999 2000 2001 2002 2003 2004
Distance (m) 39.75 41.25 40.25 40.5 43.5 43.5 41.5 45.75
Here is the scatter plot:
You are surveying students to find out their opinion of the quality of food served in the school cafeteria. You decide to poll only those students who buy hot lunch at the school on a particular day. Is your sample random? Explain.
No, the sample is not random. It is not a random sample because only the students who buy hot lunch on a particular day are being surveyed. This means that the sample is not representative of the whole student population that may have other options of buying food outside or bring food from the house. Therefore, the sample will have a bias towards the students who prefer to buy hot lunch at the school, and the information obtained from this sample cannot be generalized to the whole student population.
