In a missile-testing program, one random variable of interest is the distance between the point at which the missile lands and the center of the target at which the missile was aimed. If we think of the center of the target as the origin of a coordinate system, we can let

$$Y _ { 1 }$$

denote the north–south distance between the landing point and the target center and let

$$Y _ { 2 }$$

denote the corresponding east–west distance. (Assume that north and east define positive directions.) The distance between the landing point and the target center is then

$$U = \sqrt { Y _ { 1 } ^ { 2 } + Y _ { 2 } ^ { 2 } }$$

. If

$$Y _ { 1 } \text { and } Y _ { 2 }$$

are independent, standard normal random variables, find the probability density function for U.

An engineer selects 10 components at random and measures their strengths. It is reported that the average strength of the components is between 72.3 and 74.5 with 99$\%$ confidence. (a) What is the sample standard deviation of the 10 component strengths? (b) If a 99$\%$ two-sided confidence interval is desired with a length no longer than 1.0, about how many additional components would you recommend be tested?
