12, 26, 18, 8, 80, 14, 56, 16 the data above shows the number of points scored by each player on a basketball team during a regional tournament. jennie sampled three of the players and got a mean score of 14. charles sampled three players and got a mean score of 54. explain the difference in the two sample means.

The mean of a dataset is its average.

Jennie used small data points, while Charles used larger data points

The given parameters are:

-- sample size

For the same sample size, the higher the sample points, the higher the mean.

So the difference in the sample means implies that:

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.
