Question 1161986: In a labour management discussion it was brought up that workers at a certain large plant take on average 32.6 minutes to get to work. if a random sample of 60 workers took on the average 33.8 minutes with a standard deviation of 6.1 minutes can we reject the null hypothesis 32.6 in a faver of the alternative hypothsis >32.6 at the 0.05 level of significance? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! This is a 1 sample t-test
critical value is t>1.67
t=(x bar-mean)/s/sqrt (n)
=1.2/(6.1/sqrt(60)=1.2*sqrt(60)/6.1=1.52
This is not greater than 1.67 so insufficient evidence to reject Ho
p=0.066
