Question

5 from unit 3, lesson 1
many adults are selected at random to respond to a survey about their favorite season and whether they have allergies or not. the two - way table summarizes the results from the survey.

a. which season is the least popular in this group?
b. how many more people in this group have allergies than do not have allergies?
c. how many people were surveyed in this group?

Explanation:

Step1: Calculate the total number of people for each season

• Winter: \(43 + 21=64\)
• Spring: \(12 + 13 = 25\)
• Summer: \(35+33 = 68\)
• Fall: \(33 + 35=68\)

Step2: Calculate the number of people with allergies and without allergies

• People with allergies: \(43+12 + 35+33=123\)
• People without allergies: \(21+13+33 + 35=102\)

Step3: Calculate the total number of people surveyed

• Total \(=123 + 102=225\)

Answer:

a. Spring
b. \(123-102 = 21\)
c. \(225\)
