If the equation of the line is y=-5.9x+91.9 . Which statement is false? A. The slope of the line indicates that test score and the time spent watching tv are negatively correlated

B. The model predicts an approximate 6 - point drop in test score for one hour spent watching tv

C. The y-intercept or the line indicates that the student who spends no tv watching tv will get the highest test score possible

D. the liner model predicts an approximate test score of 92 if no time is spent watching tv

. The slope of the line indicates that test score and the time spent watching tv are negatively correlated

its D

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.
