Answer 24

directional

Question 25

What type of hypothesis should you choose to write for the following…

Answer 25

A non directional
(because although there is previous research it doesnt state a direction)

Question 27

Write a nondirectional hypothesis for the following
Redbull & No Redbull on 100m sprint in seconds

Answer 27

There will be a significant difference in running speed in seconds between those ppts that drink red bull compared to those ppts who do not drink red bull
