# Hypothesis Testing for a Chess Club Claims

A local chess club claims that the length of time to play a game has a mean of 49 minutes or more. Write sentences describing type I and type II errors for a hypothesis test o this claim.

A Type I error will occur if the actual mean of the length of time to play a game is "pick one to insert in sentence"

(less than, equal to, not equal to, less than or equal to, greater than or greater than or equal to) 49 minutes, but you (REJECT or FAIL) the null hypothesis (Ho u<49 or Ho u>49 or Ho u<_49 or Ho u>_49).

A Type II error will occur if the actual mean of the length of time to play a game is

"pick one to insert in sentence"

(less than, equal to, not equal to, less than or equal to, greater than or greater than or equal to) 49 minutes, but you (FAILED TO REJECT or REJECT) the null hypothesis (Ho u<49 or Ho u>49 or Ho u<_49 or Ho u>_49)

"pick one to insert in sentence"

(less than, equal to, not equal to, less than or equal to, greater than or greater than or equal to) 49 minutes, but you (FAILED TO REJECT or REJECT) the null hypothesis (Ho u<49 or Ho u>49 or Ho u<_49 or Ho u>_49)
