Lia and Elise are discussing measures of spread. Elise says the best measure of spread with which to compare data is the IQR. Lia says the best measure of spread with which to compare data sets is the standard deviation. Complete the sentences. Elise is correct if both data sets are

large

normal

skewed

small

2such as

1, 2, 3, 4

1, 2, 4, 5, 20, 300

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

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.
