You believe the annual mean vehicle miles of travel per household is greater than 22,000 miles. You do some research and find that a random sample of 36 US household has a mean annual VMT of 22,200 miles with a standard deviation of 775 miles. You conduct a statistical experiment where null hypothesis is less than and equal to 22,000 and alternative hypothesis is greater than 22,000. At level significance 0.05, explain why you cannot reject null hypothesis.
