The transpose of a sum of matrices equals the sum of their transposes. Choose the correct answer below.
A. The statement is false. For matrices A and B whose sizes are appropriate to sum, (Upper A + Upper B ) Superscript Upper T Baseline = Upper A Superscript Upper T Baseline - Upper B Superscript Upper T.
B. The statement is false. For matrices A and B whose sizes are appropriate to sum, (Upper A + Upper B ) Superscript Upper T Baseline = Upper A Superscript Upper T Baseline + Upper B Superscript Upper T.

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 $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 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.
