You obtain a 50-and a 100-W light bulb. Instead of connecting them in the normal way, you devise a circuit that places them in series across normal household voltage. If each one is an incandescent bulb of fixed resistance, which statement about these bulbs is correct? Both bulbs glow with the same brightness, but more than their normal brightness. The 100-W bulb glows brighter than the 50-W bulb. The 50-W bulb glows more brightly than the 100-W bulb, Both bulbs...

A truelfalse test has 100 questions. Suppose a passing grade is 60 or more correct answers. Test the claim that a student knows more than half of the answers and is not just guessing. Assume the student gets 60 answers correct out of 100. Use a significance level of 0.05. Steps 1 and 2 of a hypothesis test procedure are given below. Show step 3, finding the test statistic and the p-value and step 4, interpreting the results. Step 1:...
