A weight-loss franchise home office wanted to compare the results of two centers. Of 200 randomly selected participants from center A, 123 lost at least 10 pounds. Of 150 randomly selected participants from center B, 109 lost at least 10 pounds. Construct an 80% confidence interval for the difference between the proportions of participants at center A and participants at center B who lost at least 10 pounds. Which of the following would be the correct (generic) interpretation for this interval?

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.
