Identify which estimate seems the most reasonable for 5% tax on a $62.00 purchase. Explain. under $3.00
exactly $3.00
over $3.00
Choose the correct answer below.
A.
The most reasonable estimate is over $3.00. Since 5% of $60.00 is $4.00, 5% of $62.00 would be greater than $3.00.
B.
The most reasonable estimate is over $3.00. Since 5% of $60.00 is $3.00, 5% of $62.00 would be greater than $3.00.
C.
The most reasonable estimate is under $3.00. Since 5% of $60.00 is $3.00, 5% of $62.00 would be less than $3.00.
D.
The most reasonable estimate is exactly $3.00 since 5% of $62.00 is $3.00.

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.
