One hundred fifty students in a high school class were asked how far they lived from the school. Responses
were grouped in half-mile intervals and are shown in the histogram.
The best description of the histogram of distances is
•skewed left and single peaked
•skewed left and double peaked
•skewed right and single peaked
•skewed right and double peaked
•roughly symmetric

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

factor trees are nice.

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.
