Normally distributed student reaction time

In summary, a normally distributed student reaction time is a bell-shaped distribution of reaction times among a group of students. It can be measured using various methods and is affected by factors such as age, gender, health, and distractions. Studying it can provide insights into cognitive abilities and learning disabilities, and it can be improved through practice, training, and a healthy lifestyle.

Homework Statement
In a lab, the reaction time of the students to an event related to the experiment they are conducting is normally distributed with ##\mu=0.5## seconds, and ##\sigma=0.05## seconds.
1) What is the probability that a student will react after more than ##0.5## seconds?
2) What is the probability that a student's reaction time falls between ##0.45##, and ##0.55## seconds?
3) What is the reaction time that is exceeded ##90\%## of time?
Relevant Equations
.
1) ##P(X>0.5)=P(Z>0)=0.5##
2) ##P(0.45<X<0.55)=P(X<0.55)-P(X<0.45)=P(Z<1)-P(Z<-1)\approx68\%##
3) ##P(X>x)=0.9\Leftrightarrow P(Z>\frac{x-0.5}{0.05})=0.9\Leftrightarrow1-P(Z\leq\frac{x-0.5}{0.05})=0.9\Leftrightarrow P(Z\leq\frac{x-0.5}{0.05})=0.1##
I find that ##\frac{x-0.5}{0.05}=-1.28##, which gives me ##x=0.436##.

Correct? Thank you!

What is a normally distributed student reaction time?

A normally distributed student reaction time refers to the distribution of reaction times among a group of students that follows a normal or bell-shaped curve. This means that the majority of students have an average reaction time, with fewer students having faster or slower reaction times.

Why is it important to study normally distributed student reaction time?

Studying normally distributed student reaction time can provide valuable insights into cognitive abilities and performance. It can also help identify outliers or students with exceptionally fast or slow reaction times, which may indicate underlying issues that need to be addressed.

How is normally distributed student reaction time measured?

Normally distributed student reaction time is typically measured through a reaction time test, where students are asked to respond as quickly as possible to a stimulus. This can be done using specialized equipment or through computer-based tests.

What factors can affect normally distributed student reaction time?

There are several factors that can affect normally distributed student reaction time, including age, gender, physical and mental health, fatigue, and level of arousal. Additionally, external factors such as distractions, stress, and the complexity of the task can also impact reaction time.

How can understanding normally distributed student reaction time be applied in real-world settings?

In real-world settings, understanding normally distributed student reaction time can be useful in various fields such as education, psychology, and sports. For example, teachers can use this knowledge to identify students who may need additional support, while coaches can use it to improve the performance of athletes by identifying areas for improvement.
