Sarah collected data from her classmates, but she needs help
putting it into a two-way table.
She found that there are 8 boys that have pets and 11 girls that
have pets. She also found that there are 5 boys that do not
have pets and 6 girls do not have pets.
Organize the following data into a two-way table.

in the top left box there would be the number 8 because there are 8 boys who have pets

in the top right box there would be the number 5 because there are 5 boys who don’t have pets

in the bottom left box there would be the number 11 because there are 11 girls who have pets

in the bottom right box there would be the number 6 because there are 6 girls who don’t have pets

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
