Question 1118134:  The P-Value in your data output is ___________
 
a)The probability that you have a Type I error in your data
 
 
b)the alpha
 
 
c)the critical value
 
 
d)both the probability that you have a Type I error in your data and the alpha
 
: When you are computing a one-sample t-test, you are comparing the mean of your sample with the mean of the population. 
	a) True			b) False	
 
When you find a significant difference between the means, it is important to explain that difference in the formal report.
 
	a) True			b) False	 
 
 Answer by Boreal(15235)      (Show Source): 
You can  put this solution on YOUR website! alpha={probability reject Ho|Ho is true}, and that is fixed at the start.  We use alpha to compare the p-value to. 
This is a Type I error.  If the p-value is 0.1, that means that we would get a result this extreme or more so in 10% of the trials assuming that there is no change. That would be a Type I error. 
Critical values are of the test statistic and allow calculation of the p-value.
 
A one sample t-test does compare the mean of the sample to the mean of a population, which may not be known but is hypothesized.  True/False is difficult here, because there are important assumptions, but this is basically true. 
The last is true.
