Han is about to mow some lawns in his neighborhood. His lawn mower has a 5-gallon fuel tank, but Han is not
sure how much gasoline is in the tank.
He knows, however, that the lawn mower uses 0.4
gallon of gasolinė per hour of mowing.
Let x represent the number of hours Han can mow
without refilling the lawn mower.
Write two inequalities to represent the constraints in this
situation.

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
