Question
Types of Error: E
In a certain population, the mean mu is 45. There are one thousand statisticians, and none of them know what mu is. Each statistician takes a simple random sample from this population, and each one uses his/her sample to perform the following two-sided test:
H0: mu = 42
Ha: mu != 42
The plan is to reject the Null Hypothesis if the P-value is less than 0.05. How many of the statisticians will commit a Type-I error?
Group of answer choices
( ) About half of them
( ) None of them.
( ) All of them.
( ) About 50 of them
( ) About 100 of them.
