Create a dot plot that has at least 10 values (at least 3 that. Are different) that has a distribution which has both a mean and a median of 10. For the first and second plot what do plot, what do distribution shapes have in common? 2. What do the shapes of the dot plots have in common when the mean is greater tjan the median

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

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.
