A rocket is launched from a tower. The height of the
rocket, y in feet, is related to the time after launch, x
in seconds, by the given equation. Using this
equation, find the maximum height reached by the
rocket, to the nearest tenth of a foot.
y = β16x2 + 246x + 100
=

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 $79.79$β’79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$β’19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$β’75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$β’21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let ΞΌ1ΞΌ1 be the true mean repair cost for type i ovens and ΞΌ2ΞΌ2 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.
