As part of a math lesson on finding the average, Will's math teacher asked her students to measure the length of their calculators. This table shows the lengths they recorded. Pick all the true statements.
- Joey's calculator is the shortest
-Will's calculator is the longest
-Will's calculator is longer than Tessa's
-Damon's calculator is shorter than Tessa

Will mark brainliest! ( explain the answer too, it can be one sentence)

What is the equation of the line graphed?

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.
