A wire manufacturer is very concerned about the consistency of the machines that produce wires and believes that the wires produced by machine A have a smaller variance in diameter than the variance in diameter from machine B. The sample variance of a sample of 10 wires from machine A is 0.0347. The sample variance of a sample of 6 wires from machine B is 0.0467. Test the claim using a 0.05 level of significance. Let σ12 represent the population variance for machine A. Step 2 of 5 : Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer(s) to four decimal places.

An object is thrown upward at a speed of 53 feet per second by a machine from a height of 18 feet off the ground. The height $h$ of the object after $t$ seconds can be found using the equation $h = -16t^2 + 53t + 18$ If necessary, round your answers to the nearest hundredth (2 decimal places). When will the height be 31 feet? When will the object reach the ground?
