The football and soccer teams at juan’s middle school are selling movie tickets. he wants to determine the average number of tickets sold at the school. first, he surveyed eight random players on the football team. then, he surveyed every third athlete on the football and soccer team. which sampling technique should produce a more representative sample?

the first sampling method, surveying eight random football players, is the most representative.
neither sample will be representative.
both samples should be exactly the same.
the second sampling method, surveying the both teams, is the most representative.

The strategy that would better represent true data would be the second technique for multiple reasons. The second strategy would provide information from both the football in the soccer team. It also would provide more data points ( a larger sample group) which would increase the likelihood of the data being more accurate.

The second sampling method, surveying the both teams, is the most representative.

Step-by-step explanation:

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.
