The test statistics we use to assess a linear model are usually based on the normal distribution.
a researcher measured people's physiological reactions to horror films. he split the data into two groups: males and females. the resulting data were significantly skewed and men and women had equal variances. what test should be used to analysed the data?

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.
