The null and alternate hypotheses are: h0: Ī¼1 ā¤ Ī¼2 h1: Ī¼1 > Ī¼2 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.

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$ā¢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$ā¢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$ā¢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$ā¢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let Ī¼1Ī¼1 be the true mean repair cost for type i ovens and Ī¼2Ī¼2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
