It is known that the probability that it will fail in less than 4 hours is 0.25 a) What is the expected failure time? b) What is the probability that the component works less than the expected time?
1. Kristi knows that the average salary in her town is $35,000. She wants to know if people recently released from the local penitentiary can expect to make more or less than the average salary. Using her data below, use the appropriate statistical test to answer Kristi's research question. Assume the criterion is 0.05. (Provide a 95% confidence interval to provide evidence for your answer.) One Sample t-test Ex-Prisoner's Salary 25000 19500 35000 41500 61500 12000 26500 30900 20900 26500
A light ray (red) impacts the edge of a prism and refracts upon entry. A "normal" line (perpendicular to the boundary between air and plastic; blue) is shown at the impact boundary of the light onto the prism. 0 A OB ---OD 0c Match each of the labeled angles to those used in a Snell's Law of Refraction calculation. [Hint: All angles in a refraction calculation are measured between a light ray and a normal (perpendicular) line drawn at the impact boundary between the two materials through which the light travels (e.g., air and plastic).]
