Mark one log(OR) (b) OR We have two values for X (x=1 and x=2). What is predicted probability for each X value? With x=1, prob(Y=1|x=1)? With x=2, prob(Y=1|x=2)? Using the above estimates and

Suppose that the lifetimes of a certain kind of light bulb are normally distributed with a standard deviation of 110 hours. If exactly 98% of the bulbs die before 930 hours, find the mean lifetime of the bulbs. Carry your intermediate computations to at least four decimal places. Round your answer to at least one decimal place. ll hours X

Construct one table that includes relative frequencies based on the frequency distributions shown below, then compare the amounts of tar in nonfiltered and filtered cigarettes. Do the cigarette filters appear to be effective? (Hint: The filters reduce the amount of tar ingested by the smoker.) Click the icon to view the frequency distributions.

Logical Reasoning Directions: Indicate whether the following arguments are deductive or inductive. If the argument is deductive, specify whether it is valid or invalid, sound or not sound. If it is inductive, specify whether it is strong or weak, cogent or not cogent. (6 pts.) 1. Gas-powered cars require gas in order to start. My car's gas tank is
