1. The manager of a golf club is concerned about the length of time which some groups of players take to complete 18 holes of golf. The manager samples 24 groups, each consisting of four players, and finds the sample mean and standard deviation to be 251 minutes and 32.3 minutes respectively. Assume the length of time taken for a group of four players to complete 18 holes of golf is normally distributed a) Test to determine whether the mean length of time for all groups o four golfers to complete 18 holes is less than 265 minutes at the 10% level of significance B) What is a Type 1 Error in the context of this hypothesis test?

which some groups of players take to complete 18 holes of golf.
The manager samples 24 groups, each consisting of four players,
and finds the sample mean and standard deviation to be 251
minutes and 32.3 minutes respectively. Assume the length of time
taken for a group of four players to complete 18 holes of golf is
normally distributed
a) Test to determine whether the mean length of time for all groups of
four golfers to complete 18 holes is less than 265 minutes at the
10% level of significance
B) What is a Type 1 Error in the context of this hypothesis test?
