Assume x). decimal places. P(X > x) = 0.2946 In order to find x, first find the value z such that 29.46% of the total area under 36.32 min the standard normal density curve is to the right of z. You can find z using this Incorrect standard normal distribution table or this list of software manuals. The z-score formula, where u is the mean and o is the standard deviation, can be used to convert z into travel times. %3D Be sure to round your answer correctly to two decimal places.

- th A scientist studying babies born prematurely would like to obtain an estimate for the mean birth weight, µ, of babies born during the 24"" week of the gestation period. She plans to select a random sample of birth weights of such babies and use the mean of the sample to estimate u. Assuming that the population of th birth weights of babies born during the 24"" week has a standard deviation of 2.6 pounds, what is the minimum sample size needed for the scientist to be 95% confident that her estimate is within 0.5 pounds of µ? Carry your intermediate computations to at least three decimal places. Write your answer as a whole number (and make sure that it is the minimum whole number that satisfies the requirements).
